Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Evmos transactions ignore state changes after interacting with precompiled contracts. ๐ **Consequences**: High Integrity (I:H) & Availability (A:H) impact.โฆ
๐ก๏ธ **Root Cause**: **CWE-662** (Improper Synchronization). The flaw lies in transaction execution logic failing to account for all state transitions post-precompile interaction. ๐
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **Evmos** blockchain nodes. Specifically versions **prior to 17.0.0**. If you are running an older version, you are at risk. โ ๏ธ
Q4What can hackers do? (Privileges/Data)
๐ป **Attacker Capabilities**: Can manipulate blockchain state (I:H) and disrupt network availability (A:H). No authentication required (PR:N). Direct integrity violation. ๐
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **LOW**. CVSS indicates **AV:N** (Network), **AC:L** (Low Complexity), **PR:N** (No Privileges), **UI:N** (No User Interaction). Easy to trigger remotely. ๐ฏ
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฆ **Public Exploit**: **None listed** in current data (POCs: []). However, the low complexity suggests potential for future wild exploitation. Stay vigilant. ๐
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Verify your Evmos node version. If it is **< 17.0.0**, you are vulnerable. Check for precompiled contract interactions in your transaction logs. ๐
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix**: **YES**. Patched in **Evmos 17.0.0**. See GitHub commit `08982b5` and Advisory `GHSA-3fp5-2xwh-fxm6` for details. ๐ ๏ธ
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: Upgrade immediately. If impossible, restrict network access to trusted peers and monitor for anomalous state changes. ๐
Q10Is it urgent? (Priority Suggestion)
๐ฅ **Urgency**: **HIGH**. CVSS Score implies significant impact. With no auth required and high integrity/availability risk, patch ASAP. ๐
