Q1What is this vulnerability? (Essence + Consequences)
๐จ **Essence**: Server-Side Template Injection (SSTI) in mailcow's notification system. ๐ **Consequences**: Attackers can achieve **Remote Code Execution (RCE)**.โฆ
๐ฆ **Affected**: **mailcow: dockerized**. Specifically, versions released **before July 2025**. ๐ If you are running an older build, you are at risk. ๐ฏ
Q4What can hackers do? (Privileges/Data)
๐ **Hacker Capabilities**: With **High Privileges**, attackers can execute arbitrary code. ๐ฅ๏ธ They can steal sensitive data (C:H), modify system integrity (I:H), and disrupt availability (A:H). Itโs a full compromise. ๐
Q5Is exploitation threshold high? (Auth/Config)
๐ **Exploitation Threshold**: **Medium**. Requires **Privileged Access (PR:H)** to trigger. ๐ You cannot exploit this anonymously; you need valid credentials or elevated access to the mailcow interface first. ๐ซ
Q6Is there a public Exp? (PoC/Wild Exploitation)
๐ต๏ธ **Public Exploit**: **No**. The `pocs` field is empty. ๐ญ While advisory links exist, there is no confirmed public Proof-of-Concept (PoC) or wild exploitation code available yet. ๐ก๏ธ
Q7How to self-check? (Features/Scanning)
๐ **Self-Check**: Scan for **mailcow-dockerized** instances. ๐ก Check your version number against the July 2025 cutoff. ๐ข Look for notification features in the admin panel.โฆ
๐ฉน **Official Fix**: **Yes**. A commit exists: `8c5f6c03214a4b2bdbf3c78932f860eee949012b`. ๐ ๏ธ The vendor has acknowledged the issue via GitHub Advisory (GHSA-8p7g-6cjj-wr9m). Update immediately! ๐
Q9What if no patch? (Workaround)
๐ง **No Patch Workaround**: If you cannot update, **disable notification templates** if possible. ๐ซ Restrict access to the mailcow admin interface strictly.โฆ
๐ฅ **Urgency**: **HIGH**. Despite needing auth, the impact is **Critical** (CVSS High). ๐ RCE is a game-over scenario. Prioritize patching to prevent total server compromise. ๐โโ๏ธ๐จ
