Cisco AnyConnect Secure Mobility Client Local Privilege Escalation

Date Disclosed:
9/19/2013

Date Patched:
Patch Not Yet Available

Vendor:
Cisco

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

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.

Severity:
Moderate

Code Execution:
No.

Impact:
Privilege Escalation
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.

Mitigation:
No mitigations are currently available.

Protection:
BeyondTrust's Retina® Network Security Scanner scans devices to detect for this vulnerability.
