Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical PHP Object Injection flaw in GNUCommerce. π **Consequences**: Attackers can inject malicious objects via untrusted data deserialization, leading to full system compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-502** (Deserialization of Untrusted Data). The plugin fails to validate data before deserializing it, allowing object manipulation.
Q3Who is affected? (Versions/Components)
π’ **Affected**: **WordPress Plugin: GNUCommerce**. π¦ **Version**: 1.5.4 and all earlier versions. Vendor: kagla.
Q4What can hackers do? (Privileges/Data)
π **Impact**: High! CVSS Score is **9.8 (Critical)**. Hackers gain **Full Control** (Confidentiality, Integrity, Availability all High). They can execute arbitrary code.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. CVSS Vector: `AV:N/AC:L/PR:N/UI:N`. No authentication, no user interaction, and network-accessible. Extremely easy to exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit Status**: No specific PoC code provided in the data. However, the vulnerability type (Object Injection) is well-known and easily exploitable with standard PHP deserialization gadgets.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **GNUCommerce plugin** version **1.5.4 or lower**. Check for PHP deserialization endpoints in the plugin's codebase. Look for `unserialize()` calls on user input.
π§ **No Patch?**: Disable the plugin entirely. Remove it from the server. If it must stay, restrict network access to the WordPress admin area and implement strict WAF rules against deserialization attacks.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. CVSS 9.8 + No Auth Required = Immediate Action. Patch now to prevent remote code execution (RCE).
