Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Server-Side Template Injection (SSTI) in mailcow's notification system. π **Consequences**: Attackers can achieve **Remote Code Execution (RCE)**.β¦
π¦ **Affected**: **mailcow: dockerized**. Specifically, versions released **before July 2025**. π If you are running an older build, you are at risk. π―
Q4What can hackers do? (Privileges/Data)
π **Hacker Capabilities**: With **High Privileges**, attackers can execute arbitrary code. π₯οΈ They can steal sensitive data (C:H), modify system integrity (I:H), and disrupt availability (A:H). Itβs a full compromise. π
Q5Is exploitation threshold high? (Auth/Config)
π **Exploitation Threshold**: **Medium**. Requires **Privileged Access (PR:H)** to trigger. π You cannot exploit this anonymously; you need valid credentials or elevated access to the mailcow interface first. π«
Q6Is there a public Exp? (PoC/Wild Exploitation)
π΅οΈ **Public Exploit**: **No**. The `pocs` field is empty. π While advisory links exist, there is no confirmed public Proof-of-Concept (PoC) or wild exploitation code available yet. π‘οΈ
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for **mailcow-dockerized** instances. π‘ Check your version number against the July 2025 cutoff. π’ Look for notification features in the admin panel.β¦
π§ **No Patch Workaround**: If you cannot update, **disable notification templates** if possible. π« Restrict access to the mailcow admin interface strictly.β¦
π₯ **Urgency**: **HIGH**. Despite needing auth, the impact is **Critical** (CVSS High). π RCE is a game-over scenario. Prioritize patching to prevent total server compromise. πββοΈπ¨
