A vulnerability, which was classified as critical, has been found in Oracle MySQL Server up to 5.5.19 (Database Software). This issue affects the function acl_get of the file sql/sql_acl.cc. 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:

Stack-based buffer overflow in the acl_get function in Oracle MySQL 5.5.19 and other versions through 5.5.28, and 5.1.53 and other versions through 5.1.66, and MariaDB 5.5.2.x before 5.5.28a, 5.3.x before 5.3.11, 5.2.x before 5.2.13 and 5.1.x before 5.1.66, allows remote authenticated users to execute arbitrary code via a long argument to the GRANT FILE command.

The weakness was disclosed 12/01/2012 by kingcope as not defined exploit (Full-Disclosure). It is possible to read the advisory at seclists.org. The vendor was not involved in the public release. The identification of this vulnerability is CVE-2012-5611 since 10/24/2012. The exploitation is known to be easy. The attack may be initiated remotely. A simple authentication is needed for exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed by kingcope and been published immediately after the advisory. The exploit is available at seclists.org. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 69635 (Amazon Linux AMI : mysql51 (ALAS-2012-145)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Amazon Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 19831 (Oracle MySQL January 2013 Critical Patch Update).

Upgrading to version 5.5.28a eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (69635) and Exploit-DB (23075). The entries 7065, 7372, 7391 and 7380 are pretty similar.
