Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2007-0940.NASL description From Red Hat Security Advisory 2007:0940 : Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available. This update has been rated as having important security impact by the Red Hat Security Response Team. The Linux kernel handles the basic functions of the operating system. These new kernel packages contain fixes for the following security issues : * A flaw was found in the backported stack unwinder fixes in Red Hat Enterprise Linux 5. On AMD64 and Intel 64 platforms, a local user could trigger this flaw and cause a denial of service. (CVE-2007-4574, Important) * A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling. (CVE-2007-3848, Important) * A flaw was found in the Distributed Lock Manager (DLM) in the cluster manager. This allowed a remote user who is able to connect to the DLM port to cause a denial of service. (CVE-2007-3380, Important) * A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver which should otherwise be restricted to privileged users. (CVE-2007-4308, Moderate) * A flaw was found in the prio_tree handling of the hugetlb support that allowed a local user to cause a denial of service. This only affected kernels with hugetlb support. (CVE-2007-4133, Moderate) * A flaw was found in the eHCA driver on PowerPC architectures that allowed a local user to access 60k of physical address space. This address space could contain sensitive information. (CVE-2007-3850, Moderate) * A flaw was found in ptrace support that allowed a local user to cause a denial of service via a NULL pointer dereference. (CVE-2007-3731, Moderate) * A flaw was found in the usblcd driver that allowed a local user to cause a denial of service by writing data to the device node. To exploit this issue, write access to the device node was needed. (CVE-2007-3513, Moderate) * A flaw was found in the random number generator implementation that allowed a local user to cause a denial of service or possibly gain privileges. If the root user raised the default wakeup threshold over the size of the output pool, this flaw could be exploited. (CVE-2007-3105, Low) In addition to the security issues described above, several bug fixes preventing possible system crashes and data corruption were also included. Red Hat Enterprise Linux 5 users are advised to upgrade to these packages, which contain backported patches to resolve these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 67581 published 2013-07-12 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/67581 title Oracle Linux 5 : kernel (ELSA-2007-0940) NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2007-0940.NASL description Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available.
