Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: MDaemon IMAP Server has a **Stack Overflow** in the FETCH command.β¦
π οΈ **Root Cause**: Improper handling of **FETCH command parameters**. Specifically, the server fails to validate the length of the **BODY data item's segment identifier**.β¦
π΅οΈ **Attacker Action**: Execute **arbitrary code** on the server. ποΈ **Privileges**: Likely **System/Admin** level depending on the service account running MDaemon.β¦
π **Threshold**: **Medium**. π **Auth Required**: Yes! Attackers must possess **valid user credentials** to send the malicious FETCH command. π« **Anonymous**: No, it is not an unauthenticated exploit.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Public Exploit**: The provided data lists **no specific PoC code** (pocs array is empty).β¦
