Cisco AnyConnect Secure Mobility Client Local Privilege Escalation

Disclosed September 19, 2013    Zeroday : 751 days

Vulnerability Description:

Cisco AnyConnect for Mac OS X uses insecure permissions for a library directory, allowing local attackers to escalate their privileges via a specially crafted, strategically placed library file.



Vulnerable Software/Devices:

Cisco AnyConnect Secure Mobility Client v3.0.5080 and possibly earlier versions

Vulnerability Severity:


Exploit Availability:

Publicly Available

Exploit Impact:

Insecure Library Loading
Local attackers may place a specially crafted library file in the same folder used by AnyConnect to store library files. Because the permissions on the folder are insecure, an underprivileged attacker can place arbitrary libraries in that folder, which will then be run by AnyConnect. This allows an attacker to possibly gain access to privileged data.
