CVE-2007-0347

Status: ModifiedMedium (4.3)—💥 Exploit

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.

CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
Base score: 4.3

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 3.69%
Percentile among all scored CVEs: 89
Score date: 10/9/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

  "evaluatorImpact": "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\".",
  "evaluatorComment": "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.",
  "sourceIdentifier": "cve@mitre.org",
  "evaluatorSolution": "Successful remote unauthenticated exploit requires that CVSTrac is explicitly configured to allow anonymous users to add tickets (it is not by default)."
