CVE-2007-0347

Exp

The is_eow function in format.c in CVSTrac before 2.0.1 does not properly check for the "'" (quote) character, which allows remote authenticated users to execute limited SQL injection attacks and cause a denial of service (database error) via a ' character in certain messages, tickets, or Wiki entries.

NVD evaluator notes for CVE-2007-0347

Impact: An SQL injection via this technique is somewhat limited as is_eow() bails on whitespace. So while one _can_ do an SQL injection, one is limited to SQL queries containing only characters which get past the function isspace(3). This effectively limits attacks to SQL commands like "VACUUM".

Comment: The DoS vulnerability exists because the is_eow() function in "format.c" does NOT just check the FIRST character of the supplied string for an End-Of-Word terminating character, but instead iterates over string and this way can skip a single embedded quotation mark. The is_repository_file() function then in turn assumes that the filename string can never contain a single quotation mark and traps into a SQL escaping problem.

Solution: Successful remote unauthenticated exploit requires that CVSTrac is explicitly configured to allow anonymous users to add tickets (it is not by default).
