A vulnerability, which was classified as critical, was found in Uzbl 2009.12.22/2010.01.04/2010.04.03. This affects some unknown processing of the component Default Configuration. The manipulation of the argument HREF with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The default configuration of the <Button2> binding in Uzbl before 2010.08.05 does not properly use the @SELECTED_URI feature, which allows user-assisted remote attackers to execute arbitrary commands via a crafted HREF attribute of an A element in an HTML document.

The weakness was disclosed 08/19/2010 (Website). The advisory is shared at uzbl.org. This vulnerability is uniquely identified as CVE-2010-2809. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details and a public exploit are known. MITRE ATT&CK project uses the attack technique T1059 for this issue.

The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 48388 (Fedora 13 : uzbl-0-0.16.20100626gitafc0f873e.fc13 (2010-12260)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks.
