claudiopizzillo PIAF-HMS (PBX-In-A-Flash Hotel Management System; no released versions, latest commit 389d2633441b65ced1c104212cd62be2bfca21e5) contains multiple unauthenticated SQL injection vulnerabilities. The application has no authentication mechanism and passes user-supplied HTTP parameters directly into deprecated mysql_query() calls via string concatenation, without sanitization, escaping, or parameterization. Affected sinks include rooms.php (DELETE FROM Rooms WHERE ID = $_GET['ID'], unquoted numeric context), checkuser.php (WHERE Ext = '$_GET["Ext"]'), ec.php (date/extension parameters in a WHERE), checkin.php and wakeup.php ($_POST values into INSERT statements), bills.php ($_POST fields built into a WHERE clause), and rates.php and checkout.php. A remote, unauthenticated attacker can inject arbitrary SQL to read, modify, or delete arbitrary records in the backing database (e.g. rooms.php?ID=1 OR 1=1 deletes all room records). Note: queries run via the legacy mysql_* extension, which does not permit stacked statements.

AnalysisAI
Unauthenticated SQL injection in claudiopizzillo PIAF-HMS (PBX-In-A-Flash Hotel Management System) lets remote attackers read, modify, or delete arbitrary database records by tampering with HTTP parameters that are concatenated into legacy mysql_query() calls. The project ships with no authentication mechanism and no released versions, so any deployment exposing it to the network is fully compromisable; no public exploit identified at time of analysis, though CISA SSVC rates the technical impact as total and automatable.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default deployments of PIAF-HMS, because the application ships with no authentication layer and the vulnerable endpoints are reachable over plain HTTP to any client that can route to the web server. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H (9.3 Critical) is consistent with the description: the application has no authentication at all, so a remote attacker reaches every sink over HTTP with no prerequisites. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker scans for exposed PIAF/Asterisk admin hosts, identifies a PIAF-HMS instance, and issues GET /rooms.php?ID=1%20OR%201=1 to wipe every row in the Rooms table, or uses sqlmap against checkuser.php?Ext= to dump guest, extension, and billing records via UNION-based extraction. With no authentication and no stacked-query restriction blocking single-statement payloads, the entire database is readable and destructible in a few automated requests; no public exploit identified at time of analysis, but the bug class is trivially weaponizable with off-the-shelf tooling. |
| Remediation | No vendor-released patch identified at time of analysis - the project has no tagged releases and no fix commits referenced in the advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
