Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: WeGIA v3.2.6- has a **Code Injection** flaw. π **Consequences**: Attackers upload malicious `.phar` files via `/socio/sistema/controller/controla_xlsx.php`.β¦
π’ **Vendor**: nilsonLazarin (Personal Developer). π¦ **Product**: WeGIA (Network Manager for Welfare Institutions). π **Affected**: Versions **prior to 3.2.6**. β **Fixed**: Version 3.2.6 and later are safe.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: Full Server Control. β‘ **Impact**: CVSS Score is **High (9.8)**. Attackers can read/modify all data (C:H, I:H) and crash the system (A:H). π **Scope**: Changes affect other components (S:C).β¦
π **Auth Required**: **Yes**. PR:L (Privileges Required: Low). πΆ **Access**: You need a **valid user account** on WeGIA. π« **No Auth**: Not exploitable anonymously. πΆ **Network**: Remote (AV:N), but requires login first.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π£ **Public Exploit**: **No**. The `pocs` field is empty. π **Status**: No known public PoC or wild exploitation yet. π΅οΈββοΈ **Risk**: Low immediate threat, but high potential if exploited.
Q7How to self-check? (Features/Scanning)
π **Check**: Scan for WeGIA instances. π **Endpoint**: Look for `/html/socio/sistema/controller/controla_xlsx.php`. π€ **Test**: Try uploading a benign `.phar` file (if safe in lab).β¦
π§ **Patch**: **Yes**. Fixed in commit `a08f04de96d3caec85496d7a89a5b82d1960d9dd`. π’ **Advisory**: GHSA-mjgr-2jxv-v8qf confirms the fix. β¬οΈ **Action**: Upgrade to **WeGIA 3.2.6+** immediately.
Q9What if no patch? (Workaround)
π§ **Workaround**: If you can't patch: 1. **Restrict Uploads**: Disable file upload feature if unused. 2. **WAF**: Block `.phar` extensions at the firewall. 3.β¦
β οΈ **Urgency**: **High Priority**. π **CVSS**: 9.8 (Critical). π **Action**: Patch ASAP. Even though no public exploit exists, the flaw is trivial (Code Injection). π‘οΈ Don't wait for an attack. Secure the server now.
