Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: TRCore DVC has a critical file upload flaw. π **Consequences**: Attackers can upload **Webshells** to any directory, leading to **Arbitrary Code Execution (ACE)**. Total system compromise is possible! π
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-23** (Relative Path Traversal). π **Flaw**: The system **does not restrict file upload types**.β¦
π’ **Vendor**: TRCore. π¦ **Product**: DVC (File Insurance System). π **Affected Versions**: **6.0** through **6.3**. If you are running these versions, you are at risk! π―
Q4What can hackers do? (Privileges/Data)
