CVE-2007-0347 Detail

Description

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.


Evaluator Description

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.

Severity



CVSS 3.x Severity and Metrics:

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: NVD Analysts have not published a CVSS score for this CVE at this time. NVD Analysts use publicly available information at the time of analysis to associate CVSS vector strings.

Evaluator 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".

Evaluator Solution

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