Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: WeGIA v3.4.3- has a **SQL Injection** flaw. ๐ฅ **Consequences**: Attackers can manipulate the `id_funcionario` parameter to execute arbitrary SQL commands, compromising the entire database integrity.
Q2Root Cause? (CWE/Flaw)
๐ก๏ธ **Root Cause**: **CWE-89** (SQL Injection). The flaw stems from **improper input validation** and lack of sanitization for the `id_funcionario` parameter, allowing malicious SQL code injection.
Q3Who is affected? (Versions/Components)
๐ฅ **Affected**: **WeGIA** (Network Manager for welfare institutions) by **LabRedesCefetRJ**. Specifically, versions **prior to 3.4.3**. ๐ If you are running v3.4.2 or lower, you are at risk.
Q4What can hackers do? (Privileges/Data)
๐ต๏ธ **Attacker Capabilities**: With **High** impact (CVSS H/H/H), hackers can: ๐ **Read** sensitive employee/organizational data. ๐๏ธ **Modify** or **Delete** records.โฆ
๐ **Exploitation Threshold**: **LOW**. CVSS indicates **Network** accessible, **Low** complexity, and **No Privileges** required. ๐ No authentication or special config needed to initiate the attack vector.
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ฃ **Public Exploit**: **No**. The `pocs` field is empty. ๐ซ While the vulnerability is confirmed, there is no public Proof-of-Concept (PoC) or automated exploit kit available yet.โฆ
๐ **Self-Check**: Scan for WeGIA instances. ๐งช Test the `id_funcionario` parameter with standard SQL injection payloads (e.g., `' OR 1=1--`). Look for error messages or unexpected data responses indicating DB interaction.
Q8Is it fixed officially? (Patch/Mitigation)
โ **Official Fix**: **Yes**. A patch is available. ๐ฆ Update to **WeGIA v3.4.3** or later. The fix is documented in the GitHub advisory and commit `0a061bcc5024937edd18ab3e65ccc8f38deb6957`.
Q9What if no patch? (Workaround)
๐ **No Patch Workaround**: If you cannot update immediately: ๐ซ **Disable** the affected endpoint if possible. ๐ก๏ธ Implement **WAF rules** to block SQL injection patterns in the `id_funcionario` parameter.โฆ
๐ฅ **Urgency**: **HIGH**. CVSS Score is **9.8** (Critical). ๐จ Even without public exploits, the low barrier to entry makes this a prime target. ๐โโ๏ธ **Patch immediately** to prevent data breaches.
