Detailsinfo

A vulnerability, which was classified as problematic, has been found in IBM AIX 5.2/5.3/6.1 (Operating System). Affected by this issue is an unknown code of the component Filesystem. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality. CVE summarizes:

The proc filesystem in the kernel in IBM AIX 5.2 and 5.3 does not properly enforce directory permissions when a file executing from a directory has weaker permissions than the directory itself, which allows local users to obtain sensitive information.

The bug was discovered 03/11/2008. The weakness was published 03/31/2008 (Website). The advisory is shared for download at ibm.com. This vulnerability is handled as CVE-2008-1595 since 03/31/2008. The exploitation is known to be easy. The attack needs to be approached locally. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2008 days. During that time the estimated underground price was around $5k-$25k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (41161), SecurityFocus (BID 28467†), OSVDB (43125†), SecurityTracker (ID 1019606†) and Vulnerability Center (SBV-19233†).
