Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Server Side Include (SSI) Injection
    An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
  • Cross Zone Scripting
    An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
  • Cross Site Scripting through Log Files
    An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
  • Command Line Execution through SQL Injection
    An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

    descriptionAn update for quagga is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The quagga packages contain Quagga, the free network-routing software suite that manages TCP/IP based protocols. Quagga supports the BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, and RIPng protocols, and is intended to be used as a Route Server and Route Reflector. Security Fix(es) : * A stack-based buffer overflow flaw was found in the way Quagga handled IPv6 router advertisement messages. A remote attacker could use this flaw to crash the zebra daemon resulting in denial of service. (CVE-2016-1245) * A stack-based buffer overflow flaw was found in the way the Quagga BGP routing daemon (bgpd) handled Labeled-VPN SAFI routes data. A remote attacker could use this flaw to crash the bgpd daemon resulting in denial of service. (CVE-2016-2342) * A denial of service flaw was found in the Quagga BGP routing daemon (bgpd). Under certain circumstances, a remote attacker could send a crafted packet to crash the bgpd daemon resulting in denial of service. (CVE-2016-4049) * A denial of service flaw affecting various daemons in Quagga was found. A remote attacker could use this flaw to cause the various Quagga daemons, which expose their telnet interface, to crash. (CVE-2017-5495) * A stack-based buffer overflow flaw was found in the way the Quagga OSPFD daemon handled LSA (link-state advertisement) packets. A remote attacker could use this flaw to crash the ospfd daemon resulting in denial of service. (CVE-2013-2236) Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.

    descriptionThe remote NewStart CGSL host, running version MAIN 4.05, has quagga packages installed that are affected by multiple vulnerabilities: - A denial of service flaw affecting various daemons in Quagga was found. A remote attacker could use this flaw to cause the various Quagga daemons, which expose their telnet interface, to crash. (CVE-2017-5495) - A stack-based buffer overflow flaw was found in the way Quagga handled IPv6 router advertisement messages. A remote attacker could use this flaw to crash the zebra daemon resulting in denial of service. (CVE-2016-1245) - A denial of service flaw was found in the Quagga BGP routing daemon (bgpd). Under certain circumstances, a remote attacker could send a crafted packet to crash the bgpd daemon resulting in denial of service. (CVE-2016-4049) - A stack-based buffer overflow flaw was found in the way the Quagga BGP routing daemon (bgpd) handled Labeled-VPN SAFI routes data.

    descriptionAccording to the versions of the quagga package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - Open Shortest Path First (OSPF) protocol implementations may improperly determine Link State Advertisement (LSA) recency for LSAs with MaxSequenceNumber. According to RFC 2328 section 13.1, for two instances of the same LSA, recency is determined by first comparing sequence numbers, then checksums, and finally MaxAge. In a case where the sequence numbers are the same, the LSA with the larger checksum is considered more recent, and will not be flushed from the Link State Database (LSDB). Since the RFC does not explicitly state that the values of links carried by a LSA must be the same when prematurely aging a self-originating LSA with MaxSequenceNumber, it is possible in vulnerable OSPF implementations for an attacker to craft a LSA with MaxSequenceNumber and invalid links that will result in a larger checksum and thus a
