CVE-2021-29156 — AI Deep Analysis Summary

🚨 **Essence**: LDAP Injection in ForgeRock OpenAM. 📉 **Consequences**: Attackers can extract password hashes character-by-character, steal session tokens, or retrieve private keys.…

🛡️ **Root Cause**: LDAP Injection. 🐛 **Flaw**: Backend validates user existence via LDAP query during password reset. ⚠️ **CWE**: Not explicitly listed, but classic injection flaw in input handling.

🏢 **Vendor**: ForgeRock. 📦 **Product**: OpenAM (SSO Framework). 📅 **Affected**: Versions **before 13.5.1** (e.g., v13.0.0). 🌐 **Scope**: CoreServer identity service.

🕵️ **Actions**: Enumerate users & retrieve data. 🔑 **Data Stolen**: Password hashes (char-by-char), Session Tokens, Private Keys. 🚪 **Privileges**: Can bypass authentication checks via token theft.

⚖️ **Threshold**: Medium. 📝 **Auth**: Likely requires initial access to the password reset flow. ⚙️ **Config**: Exploits the LDAP query logic during user validation. 📧 **Vector**: Triggered via password reset request.

🔓 **Public Exp?**: YES. 🛠️ **PoCs**: Multiple available (GuidePoint Security, 5amu, Nuclei templates). 🌍 **Wild Exp**: Active exploitation tools exist and are functional. ⚡ **Ease**: Automated scripts available.

🔍 **Check**: Scan for OpenAM v13.0.0-13.5.0. 🧪 **Test**: Use Nuclei templates or specific PoC tools. 📧 **Indicator**: Observe LDAP query behavior during password reset attempts.…

✅ **Fixed**: YES. 📦 **Patch**: Upgrade to **OpenAM 13.5.1** or later. 📜 **Ref**: Bugster OPENAM-10135. 🔄 **Action**: Immediate update recommended.

🚧 **Workaround**: If patching is delayed, restrict access to password reset endpoints. 🛑 **Mitigation**: Implement strict input validation on LDAP queries. 📉 **Limit**: Reduce exposure of the CoreServer interface.…

🔥 **Urgency**: HIGH. 🚨 **Priority**: Critical. ⏳ **Reason**: Active PoCs exist, sensitive data (hashes/keys) is at risk. 🏃 **Action**: Patch immediately or apply mitigations. 📢 **Alert**: Notify security teams now.
