Message | IMAP auth overflow attempt |
Summary | This event is generated when a remote user sends an overly long string to an IMAP server via the command AUTH. This may indicate an attempt to exploit a buffer overflow condition. |
Impact | Serious. Possible remote execution of arbitrary code, which may lead to a remote root compromise. |
Detailed Information | When a large amount of data is sent to a vulnerable IMAP server in the AUTHENTICATE command, a buffer overflow condition may occur. This can allow the attacker to execute arbitrary code, which may allow the attacker to gain root access to the compromised server. |
Affected Systems | IMAP servers |
Attack Scenarios | An attacker can send a sufficiently long AUTHENTICATE command to the IMAP server, creating a buffer overflow condition. This can then allow the attacker to execute code of their choosing and possibly gain root access to the compromised server. |
Ease of Attack | Simple. Exploits exist. |
Corrective Action | Apply the appropriate patches for your operating system. Check the host for signs of compromise. |
