Detailsinfo

A vulnerability was found in UMN MapServer up to 5.4.1 and classified as very critical. This issue affects the function readPostBody of the file cgiutil.c. 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:

Multiple heap-based buffer underflows in the readPostBody function in cgiutil.c in mapserv in MapServer 4.x through 4.10.4 and 5.x before 5.4.2 allow remote attackers to execute arbitrary code via (1) a crafted Content-Length HTTP header or (2) a large HTTP request, related to an integer overflow that triggers a heap-based buffer overflow. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2009-0840.

The weakness was published 10/23/2009 with Debian (Website). The advisory is shared at security.debian.org. The identification of this vulnerability is CVE-2009-2281 since 07/01/2009. 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 known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/24/2021).

The vulnerability scanner Nessus provides a plugin with the ID 44779 (Debian DSA-1914-1 : mapserver - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks.

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