Detailsinfo

A vulnerability was found in Sun Solaris 7.0 (Operating System). It has been rated as critical. This issue affects an unknown code. The manipulation of the argument TZ as part of a Environment Variable leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in ipcs in Solaris 7 x86 allows local users to execute arbitrary code via a long TZ (timezone) environmental variable, a different vulnerability than CAN-2002-0093.

The bug was discovered 04/12/2001. The weakness was disclosed 07/02/2001 by Riley Hassell with eEye (Website). The advisory is shared at archives.neohapsis.com. The identification of this vulnerability is CVE-2001-0423. The exploitation is known to be easy. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

The exploit is available 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 81 days. During that time the estimated underground price was around $25k-$100k.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (9613), Exploit-DB (20751), SecurityFocus (BID 2581†), OSVDB (8685†) and Vulnerability Center (SBV-20819†).
