Detailsinfo

A vulnerability, which was classified as critical, has been found in Pico Server up to 2.0beta5. This issue affects an unknown functionality. The manipulation with an unknown input 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 Pico Server (pServ) 2.0 beta 1 through beta 5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) a 1024-byte TCP stream message, which triggers an off-by-one buffer overflow, or (2) a long method name in an HTTP request, (3) a long version number in an HTTP request, (4) a long User-Agent header, or (5) a long file path.

The weakness was disclosed 12/31/2002 by Matthew Murphy (mattmurphy) (Website). The advisory is shared at derkeiler.com. The identification of this vulnerability is CVE-2002-2295 since 10/17/2007. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

The exploit is available at exploit-db.com. It is declared as proof-of-concept.

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 (10789), Exploit-DB (22056) and SecurityFocus (BID 6285†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
