A vulnerability was found in Acme Labs thttpd 2.25b (Web Server). It has been classified as critical. This affects an unknown part of the component setuid Program. The manipulation of the argument line 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 htpasswd, as used in Acme thttpd 2.25b, and possibly other products such as Apache, might allow local users to gain privileges via (1) a long command line argument and (2) a long line in a file. NOTE: since htpasswd is normally installed as a non-setuid program, and the exploit is through command line options, perhaps this issue should not be included in CVE. However, if there are some typical or recommended configurations that use htpasswd with sudo privileges, or common products that access htpasswd remotely, then perhaps it should be included.

The weakness was disclosed 03/08/2006 by Larry Cashdollar (Website). It is possible to read the advisory at securityfocus.com. This vulnerability is uniquely identified as CVE-2006-1078 since 03/08/2006. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 97144 (Acme thttpd < 2.26 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Web Servers and running in the context r.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (31236) and Tenable (97144). The entry 29068 is pretty similar.
