A vulnerability, which was classified as critical, has been found in Squash Square Squash (the affected version unknown). Affected by this issue is the function sourcemap. The manipulation of the argument sourcemap with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. CVE summarizes:

The Square Squash allows remote attackers to execute arbitrary code via a YAML document in the (1) namespace parameter to the deobfuscation function or (2) sourcemap parameter to the sourcemap function in app/controllers/api/v1_controller.rb.

The weakness was disclosed 05/27/2014 (Website). The advisory is available at github.com. This vulnerability is handled as CVE-2013-5036 since 08/06/2013. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details as well as a public exploit are known. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

A public exploit has been developed by Metasploit and been published before and not just after the advisory. The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 288 days. During that time the estimated underground price was around $0-$5k.

The vulnerability is also documented in the databases at X-Force (86335) and Exploit-DB (27530).
