Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: OpenProject SQL Injection via `=n` operator. <br>๐ฅ **Consequences**: Attackers inject malicious SQL into WHERE clauses. <br>๐ **Impact**: Data theft, integrity loss, or system compromise.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **CWE-89**: SQL Injection. <br>๐ **Flaw**: User input is directly embedded into SQL queries. <br>โ **Root**: Lack of parameterization for the `=n` operator.
Q3Who is affected? (Versions/Components)
๐ข **Vendor**: OpenProject (opf). <br>๐ฆ **Product**: OpenProject Web App. <br>โ ๏ธ **Affected**: Versions **prior to 17.2.3**.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Privileges**: Requires Low Privilege (PR:L). <br>๐ **Data**: Can read (C:L), modify (I:H), or delete (A:H) data. <br>๐ **Scope**: Affects other security components (S:C).
Q5Is exploitation threshold high? (Auth/Config)
๐ **Auth**: Yes, requires **Low Privilege** authentication. <br>๐ **Network**: Remote (AV:N). <br>๐ถ **Complexity**: Low (AC:L), no user interaction needed (UI:N).
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ **PoC**: No public PoC listed in data. <br>๐ฅ **Wild Exploit**: Unconfirmed. <br>๐ **Ref**: Check GitHub Advisory GHSA-5rrm-6qmq-2364.
Q7How to self-check? (Features/Scanning)
๐ **Check**: Scan for OpenProject instances. <br>๐งช **Test**: Verify version < 17.2.3. <br>๐ **Log**: Monitor SQL error logs for injection attempts.
