HP Tru64 up to 5.1af su/chsh/passwd/chfn/dxchpwd/libc memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in HP Tru64 4.0f/4.0g/5.0a/5.1/5.1af. It has been classified as critical. This affects an unknown part of the component su/chsh/passwd/chfn/dxchpwd/libc. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in HP Tru64 UNIX 5.1a, 5.1, 5.0a, 4.0g, and 4.0f allow local users to gain root privileges via (1) su, (2) chsh, (3) passwd, (4) chfn, (5) dxchpwd, and (6) libc.

The weakness was presented 09/03/2002 as confirmed advisory (CERT.org). It is possible to read the advisory at kb.cert.org. This vulnerability is uniquely identified as CVE-2002-1616 since 03/25/2005. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by K2 and been published before and not just after the advisory. The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 552 days. During that time the estimated underground price was around $25k-$100k.

The vulnerability is also documented in the databases at X-Force (10614), Exploit-DB (259), SecurityFocus (BID 5382†) and OSVDB (18203†). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
