CVE-2011-4693

Vulnerability

An unspecified vulnerability exists in Adobe Flash Player version 11.1.102.55 on Windows and Mac OS X. The flaw is triggered by a crafted SWF file. The exact nature of the vulnerability is not disclosed. It is unclear whether Linux is also affected [1].

Exploitation

An attacker can exploit this vulnerability by hosting a malicious SWF file and convincing a user to open it in a vulnerable Flash Player instance. No authentication or special network position is required beyond delivering the SWF file to the target. The exploit was demonstrated by the Intevydis vd_adobe_fp module in VulnDisco Step Ahead (SA) [1].

Impact

Successful exploitation allows remote attackers to execute arbitrary code on the affected system with the privileges of the user running Flash Player. This can lead to full compromise of the user's data and system [1].

Mitigation

As of the publication date, no patch or fix is available. Red Hat has stated they do not plan to fix this issue due to lack of further information [1]. Users are advised to disable or restrict Flash Player usage until a fix is released. The vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog.
