AnalysisAI

Unauthenticated OS command injection in the ping.php endpoint of Trexom's TrxTimeATTENDANCE (versions 1.0.5 through 1.9.5, fixed in 1.9.6) allows any remote attacker who can reach the endpoint to execute arbitrary operating-system commands and obtain remote code execution with the privileges of the web server process. The flaw, classified CWE-78 and scored 9.3 under CVSS 4.0, is remotely exploitable with no authentication or user interaction (PR:N/UI:N/AC:L), and publicly available exploit code exists, elevating the risk for any instance exposed beyond a trusted LAN. …

Vulnerability AssessmentAI

Exploitation Exploitation requires network reachability to the application's ping.php endpoint on an affected TrxTimeATTENDANCE instance (versions 1.0.5 up to but not including 1.9.6). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment This is a genuinely high-priority issue where the signals largely align. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Apply the vendor fix by upgrading TrxTimeATTENDANCE to version 1.9.6 or later, which removes the ping.php command-injection flaw; the vendor's development/advisory page (https://www.trexom.net/sviluppo-di-app/) and the Italian ACN security-update notice (https://www.acn.gov.it/portale/w/trexom-aggiornamenti-di-sicurezza) are the authoritative sources for the patched build. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, inventory every TrxTimeATTENDANCE instance, confirm whether it is running version 1.0.5 through 1.9.5, and for any internet-facing or untrusted-network-accessible deployment either apply the vendor-released patch to 1.9.6 or isolate the system and block access to ping.php until patching can be completed; also search web server and application logs for suspicious requests to ping.php and unusual child processes. …
