Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Authenticated Remote Code Execution (RCE) in Widget Options plugin. π₯ **Consequences**: Attackers can inject arbitrary PHP code, leading to full server compromise, data theft, or site defacement.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: CWE-94 (Code Injection). The `widgetopts_safe_eval()` function improperly evaluates user-supplied input in the widget `logic` feature without proper sanitization.
π΅οΈ **Attacker Actions**: Execute arbitrary PHP code on the server. π **Impact**: Full control over the website, access to sensitive data, and potential lateral movement within the network.
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: Medium. Requires **Authentication**. βοΈ **Privileges**: Minimum **Contributor** role or higher. Not open to anonymous users.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π» **Exploit Status**: Yes, public PoC exists. π **Link**: GitHub repo by Chocapikk demonstrates authenticated RCE. Wild exploitation is likely given the low barrier.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for installed version of Widget Options. π§ͺ **Test**: Check if `widgetopts_safe_eval` is callable by Contributor users in the logic settings. Use vulnerability scanners targeting WordPress plugins.
π§ **No Patch?**: Disable the plugin entirely. π **Mitigation**: Restrict Contributor+ roles if possible. Remove widget logic features if not needed. Monitor server logs for suspicious PHP execution.
Q10Is it urgent? (Priority Suggestion)
π₯ **Priority**: **CRITICAL**. CVSS Score indicates High impact (C:H, I:H, A:H). Even though auth is required, Contributor accounts are often compromised. Patch immediately!
