CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-50094 is a high-severity OS Command Injection (CWE-78) vulnerability in Yogeshojha Rengine. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
reNgine versions prior to 2.1.2 contain an OS command injection vulnerability tracked as CVE-2023-50094 and CWE-78. The flaw resides in the api/tools/waf_detector endpoint, where unsanitized input supplied to the url parameter is passed directly to subprocess.check_output, allowing shell metacharacters to be interpreted and executed with root privileges.
An authenticated attacker possessing a valid session ID can exploit the issue over the network by crafting a malicious url value. Successful exploitation yields arbitrary command execution on the underlying host, resulting in full confidentiality, integrity, and availability impact as reflected by the CVSS 3.1 base score of 8.8.
The referenced commits 3d5f1724dd12cf9861443742e7d7c02ff8c75a6f and edd3c85ee16f93804ad38dac5602549d2d30a93e, together with the 2.1.2 release, address the injection by correcting the handling of the affected API view. The current EPSS score of 0.8856 with a recorded peak of 0.9249 indicates sustained exploitation interest after disclosure.

Vulnerability Data
reNgine before 2.1.2 allows OS Command Injection if an adversary has a valid session ID. The attack places shell metacharacters in an api/tools/waf_detector/?url= string. The commands are executed as root via subprocess.check_output.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
