Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Unauthenticated PHP Object Injection via untrusted data deserialization. π₯ **Consequences**: Attackers can inject PHP objects.β¦
π‘οΈ **Root Cause**: **CWE-502** (Deserialization of Untrusted Data). The plugin fails to validate input before passing it to PHP's `unserialize()` function, allowing malicious object injection.
Q3Who is affected? (Versions/Components)
π¦ **Affected**: **Lis Video Gallery** WordPress plugin. π **Versions**: 0.2.1 and earlier. π’ **Vendor**: bublick.
Q4What can hackers do? (Privileges/Data)
π **Attacker Capabilities**: Unauthenticated access. Potential for: π Deleting arbitrary files, π Retrieving sensitive data, π» Executing arbitrary code (if a POP chain is present in the site's theme/other plugins).
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **LOW**. No authentication required (PR:N). Low complexity (AC:L). No user interaction needed (UI:N). CVSS Score is **Critical (9.8)**.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π₯ **Exploit Status**: **YES**. Public PoC available on GitHub (RandomRobbieBF). Described as "Unauthenticated PHP Object Injection".
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **Lis Video Gallery** plugin version β€ 0.2.1. Check for unauthenticated endpoints accepting serialized PHP data. Use vulnerability scanners detecting CWE-502.
π§ **No Patch Workaround**: Disable the plugin if not needed. Implement WAF rules to block serialized PHP payloads in request parameters. Restrict file permissions to prevent deletion.
Q10Is it urgent? (Priority Suggestion)
β‘ **Priority**: **CRITICAL**. CVSS 9.8. Unauthenticated RCE potential. Patch immediately. High risk of exploitation due to low barrier to entry.
