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.

| description | Updated packages that fix several security issues and add one enhancement are now available for Red Hat Network Satellite 5.4.1 for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Red Hat Network (RHN) Satellite provides a solution to organizations requiring absolute control over and privacy of the maintenance and package deployment of their servers. It allows organizations to utilize the benefits of the Red Hat Network without having to provide public Internet access to their servers or other client systems. Multiple cross-site scripting (XSS) flaws were found in the RHN Satellite web interface. A remote attacker could use these flaws to perform a cross-site scripting attack against victims using the RHN Satellite web interface. (CVE-2011-2919, CVE-2011-2920, CVE-2011-2927, CVE-2011-3344) An open redirect flaw was found in the RHN Satellite web interface login page. A remote attacker able to trick a victim to open the login page using a specially crafted link could redirect the victim to an arbitrary page after they successfully log in. (CVE-2011-1594) Red Hat would like to thank Daniel Karanja Muturi for reporting CVE-2011-2919; Nils Juenemann and The Bearded Warriors for independently reporting CVE-2011-2920; Nils Juenemann for reporting CVE-2011-2927; Sylvain Maes for reporting CVE-2011-3344; and Thomas Biege of the SuSE Security Team for reporting CVE-2011-1594. This update also adds the following enhancement : * Session cookies set by RHN Satellite are now marked as HTTPOnly. This setting helps reduce the impact of cross-site scripting flaws by instructing the browser to disallow scripts access to those cookies. (BZ#713477) Users of Red Hat Network Satellite 5.4.1 are advised to upgrade to these updated packages, which contain patches to correct these issues and add this enhancement. For this update to take effect, Red Hat Network Satellite must be restarted. Refer to the Solution section for details. |
