Exploitation requires writing an unsigned plugin into the plugin directory, implying local access with some privilege (AV:L/PR:L); loaded code yields full C/I/A loss in the CLI process.

3DescriptionCVE.org
openssl_encrypt versions before 1.4.9 use a denylist to identify trusted built-in plugins, allowing unsigned plugins in top-level plugins/ directories and unknown subdirectories to bypass signature verification. Attackers can place malicious unsigned plugins following documented installation paths to achieve arbitrary code execution in the CLI process with access to passwords and cryptographic keys.
AnalysisAI
Arbitrary code execution in jahlives openssl_encrypt before 1.4.9 stems from a flawed plugin trust model that uses a denylist rather than an allowlist to identify built-in plugins, so unsigned plugins dropped into top-level plugins/ directories or unrecognized subdirectories evade signature verification entirely. An attacker who can place a malicious plugin along documented installation paths gains code execution inside the CLI process, exposing user passwords and cryptographic keys. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to place a malicious, unsigned plugin file into a top-level plugins/ directory or an unknown plugin subdirectory following the tool's documented installation paths - this is the exact prerequisite named in the description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are partly conflicting and must be weighed carefully. … 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 | Vendor-released patch: upgrade to openssl_encrypt 1.4.9 or later, which corrects the plugin trust model so signature verification is enforced on plugins in top-level plugins/ directories and unknown subdirectories; see the advisory at https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-wxx9-p55f-wm34. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all systems running jahlives openssl_encrypt versions before 1.4.9 and immediately restrict write permissions on plugin installation directories to prevent unauthorized file placement. …
