Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability is a command injection flaw (CWE-78) in the c_rehash shell script distributed with OpenSSL. It stems from incomplete sanitization of shell metacharacters in certificate file names passed to executed commands, an issue that remained after the partial fix for the related CVE-2022-1292. Affected versions include OpenSSL 3.0.0 through 3.0.3, 1.1.1 through 1.1.1o, and 1.0.2 through 1.0.2ze; the script is shipped by some operating systems in a way that triggers automatic execution.
A local attacker who can supply or influence certificate files processed by c_rehash can inject and execute arbitrary commands under the privileges of the script. This occurs without requiring elevated privileges beyond local access and user interaction to trigger the script, potentially leading to full control over the affected system components.
Advisories and patches recommend replacing use of the obsolete c_rehash script with the OpenSSL rehash command-line tool. Fixes are available in OpenSSL 3.0.4, 1.1.1p, and 1.0.2zf, with additional vendor guidance such as the Siemens SSA-332410 advisory and distribution-specific notices like the Fedora package announcement.
The EPSS score reached a peak of 0.2354 with a current value of 0.2022.

Vulnerability Data
In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. When the CVE-2022-1292 was fixed it was not…

discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze).

Mitigating Controls (NIST 800-53 r5) AI
Directly requires timely application of vendor patches that remediate the c_rehash command-injection flaw in the listed OpenSSL versions.
Mandates disabling or removing non-essential components; the obsolete c_rehash script must be replaced by the OpenSSL rehash tool to eliminate the attack surface.
Requires validation and sanitization of untrusted input (certificate file names) before they are passed to shell commands, blocking the CWE-78 injection vector.

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).
