Cacti · Cacti · CVE-2026-71287
**Name of the Vulnerable Software and Affected Versions**
Cacti (affected versions not specified)
**Description**
The `sanitize sql column()` function in `lib/functions.php` fails to properly sanitize user-supplied ORDER BY column names. The function uses a regular expression that allows letters, digits, underscores, parentheses, and dots, which enables payloads like `SLEEP(5)` to pass unmodified. This sanitized value is concatenated directly into raw SQL ORDER BY clauses via the `sort column` GET parameter in the endpoints 'user log.php', 'utilities.php', 'user domains.php', and 'user group admin.php'. Consequently, any authenticated user can perform time-based blind SQL injection, a technique used to extract information from a database by observing the time it takes for the server to respond to specific queries.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
