Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: SOFA-Hessian has a **Deserialization Injection** flaw. π **Consequences**: Attackers bypass blacklists to execute arbitrary code. π₯ **Impact**: Full system compromise via binary serialization protocol.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **CWE**: CWE-74 (Improper Neutralization). π **Flaw**: The deserialization logic fails to properly validate input, allowing malicious objects to bypass security filters.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: SOFAStack. π¦ **Product**: sofa-hessian. β οΈ **Affected**: Versions **prior to 3.5.4**. β **Safe**: v3.5.4 and above.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Remote Code Execution (RCE). π **Data**: High Confidentiality, Integrity, and Availability loss. π― **Result**: Complete server takeover.
Q5Is exploitation threshold high? (Auth/Config)
π **Auth**: None required (PR:N). π **Network**: Network accessible (AV:N). π **Threshold**: **LOW**. Easy to exploit remotely without user interaction.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp**: No specific PoC listed in data. π **Status**: Advisory published. β οΈ **Risk**: High likelihood of wild exploitation due to low barrier.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for SOFA-Hessian usage. π **Version**: Verify if version < 3.5.4. π οΈ **Tool**: Use SAST/DAST scanners targeting deserialization flaws.
