CVE-2026-28805 | OpenSTAManager: Time-Based Blind SQL Injection via `options[stato]` Parameter

Exp

OpenSTAManager is an open source management software for technical assistance and invoicing. Prior to version 2.10.2, multiple AJAX select handlers in OpenSTAManager are vulnerable to Time-Based Blind SQL Injection through the options[stato] GET parameter. The user-supplied value is read from $superselect['stato'] and concatenated directly into SQL WHERE clauses as a bare expression, without any sanitization, parameterization, or allowlist validation. An authenticated attacker can inject arbitrary SQL statements to extract sensitive data from the database, including usernames, password hashes, financial records, and any other information stored in the MySQL database. This issue has been patched in version 2.10.2.

8.8 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
