Open ISES Tickets SQL Injection (CVE-2026-48236) Exposes Databases

Open ISES Tickets SQL Injection (CVE-2026-48236) Exposes Databases

The National Vulnerability Database has detailed CVE-2026-48236, a high-severity SQL injection vulnerability affecting Open ISES Tickets before version 3.44.2. The flaw resides in db_loader.php, where multiple POST parameters—ticketsdb, ticketshost, ticketsuser, and ticketspassword—are directly concatenated into mysqli connection arguments. This lack of sanitization allows authenticated attackers to manipulate these parameters.

Attackers can craft malicious requests that alter SQL query semantics, effectively executing arbitrary SQL commands against an attacker-controlled database. This grants them the ability to read, modify, or destroy database contents, leading to significant data compromise. The National Vulnerability Database assigns this a CVSSv3.1 score of 7.1 (HIGH), with a vector of AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N, highlighting the high impact on confidentiality.

While specific affected products beyond ‘Open ISES Tickets’ are not detailed by the National Vulnerability Database, organizations using this software are at direct risk. This vulnerability is a classic CWE-89 SQL injection, a perennial problem that continues to plague applications. The attacker’s calculus here is straightforward: leverage authenticated access to pivot from application control to database control, extracting or corrupting critical data.

What This Means For You

  • If your organization uses Open ISES Tickets, you must immediately verify your version. Patch to 3.44.2 or later without delay to mitigate CVE-2026-48236. Audit logs for any anomalous database activity, especially around `db_loader.php` interactions or unusual SQL errors, which could indicate attempted exploitation.
