Common Attack Pattern Enumeration and Classification (CAPEC)

  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.

    descriptionMultiple vulnerabilities has been found and corrected in the Linux kernel : The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h (CVE-2013-2929). The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application (CVE-2013-2930). Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the (1) au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in drivers/video/au1200fb.c (CVE-2013-4511). Buffer overflow in the exitcode_proc_write function in arch/um/kernel/exitcode.c in the Linux kernel before 3.12 allows local users to cause a denial of service or possibly have unspecified other impact by leveraging root privileges for a write operation (CVE-2013-4512). Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions (CVE-2013-4514). The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in the Linux kernel before 3.12 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call (CVE-2013-4515). Memory leak in the __kvm_set_memory_region function in virt/kvm/kvm_main.c in the Linux kernel before 3.9 allows local users to cause a denial of service (memory consumption) by leveraging certain device access to trigger movement of memory slots (CVE-2013-4592). The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-length write operation (CVE-2013-6378). The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 3.12.1 does not properly validate a certain size value, which allows local users to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via an FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command (CVE-2013-6380). Buffer overflow in the qeth_snmp_command function in drivers/s390/net/qeth_core_main.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service or possibly have unspecified other impact via an SNMP ioctl call with a length value that is incompatible with the command-buffer size (CVE-2013-6381). The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux kernel before 3.11.8 does not require the CAP_SYS_RAWIO capability, which allows local users to bypass intended access restrictions via a crafted ioctl call (CVE-2013-6383). The uio_mmap_physical function in drivers/uio/uio.c in the Linux kernel before 3.12 does not validate the size of a memory block, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via crafted mmap operations, a different vulnerability than CVE-2013-4511 (CVE-2013-6763). The updated packages provides a solution for these security issues.

  • NASL familySuSE Local Security Checks
    NASL idSUSE_11_KERNEL-140125.NASL
    descriptionThe SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to 3.0.101 and also includes various other bug and security fixes. A new feature was added : - supported.conf: marked net/netfilter/xt_set as supported (bnc#851066)(fate#313309) The following security bugs have been fixed : - Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value. (bnc#853050). (CVE-2013-4587) - Memory leak in the __kvm_set_memory_region function in virt/kvm/kvm_main.c in the Linux kernel before 3.9 allows local users to cause a denial of service (memory consumption) by leveraging certain device access to trigger movement of memory slots. (bnc#851101). (CVE-2013-4592) - The apic_get_tmcct function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via crafted modifications of the TMICT value. (bnc#853051). (CVE-2013-6367) - The KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address. (bnc#853052). (CVE-2013-6368) - The recalculate_apic_map function in arch/x86/kvm/lapic.c in the KVM subsystem in the Linux kernel through 3.12.5 allows guest OS users to cause a denial of service (host OS crash) via a crafted ICR write operation in x2apic mode. (bnc#853053). (CVE-2013-6376) - The ipc_rcu_putref function in ipc/util.c in the Linux kernel before 3.10 does not properly manage a reference count, which allows local users to cause a denial of service (memory consumption or system crash) via a crafted application. (bnc#848321). (CVE-2013-4483) - Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the (1) au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in drivers/video/au1200fb.c. (bnc#849021). (CVE-2013-4511) - Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions. (bnc#849029). (CVE-2013-4514) - The bcm_char_ioctl function in drivers/staging/bcm/Bcmchar.c in the Linux kernel before 3.12 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an IOCTL_BCM_GET_DEVICE_DRIVER_INFO ioctl call. (bnc#849034). (CVE-2013-4515) - The lbs_debugfs_write function in drivers/net/wireless/libertas/debugfs.c in the Linux kernel through 3.12.1 allows local users to cause a denial of service (OOPS) by leveraging root privileges for a zero-length write operation. (bnc#852559). (CVE-2013-6378) - The aac_send_raw_srb function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 3.12.1 does not properly validate a certain size value, which allows local users to cause a denial of service (invalid pointer dereference) or possibly have unspecified other impact via an FSACTL_SEND_RAW_SRB ioctl call that triggers a crafted SRB command. (bnc#852373). (CVE-2013-6380) - The ieee80211_radiotap_iterator_init function in net/wireless/radiotap.c in the Linux kernel before 3.11.7 does not check whether a frame contains any data outside of the header, which might allow attackers to cause a denial of service (buffer over-read) via a crafted header. (bnc#854634). (CVE-2013-7027) - Linux kernel built with the networking support(CONFIG_NET) is vulnerable to an information leakage flaw in the socket layer. It could occur while doing recvmsg(2), recvfrom(2) socket calls. It occurs due to improperly initialised msg_name & msg_namelen message header parameters. (bnc#854722). (CVE-2013-6463) - The aac_compat_ioctl function in drivers/scsi/aacraid/linit.c in the Linux kernel before 3.11.8 does not require the CAP_SYS_RAWIO capability, which allows local users to bypass intended access restrictions via a crafted ioctl call. (bnc#852558). (CVE-2013-6383) - Off-by-one error in the get_prng_bytes function in crypto/ansi_cprng.c in the Linux kernel through 3.11.4 makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via multiple requests for small amounts of data, leading to improper management of the state of the consumed data. (bnc#840226). (CVE-2013-4345) - arch/x86/kernel/cpu/perf_event_intel.c in the Linux kernel before 3.8.9, when the Performance Events Subsystem is enabled, specifies an incorrect bitmask, which allows local users to cause a denial of service (general protection fault and system crash) by attempting to set a reserved bit. (bnc#825006). (CVE-2013-2146) - The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application. (bnc#849362).
