Message | FTP CEL overflow attempt |
Summary | This event is generated when a remote attacker attempts to exploit a buffer overflow vulnerability in the IBM AIX FTP daemon.
|
Impact | Remote execution of arbitrary code leading to remote root compromise.
|
Detailed Information | The IBM AIX 4.3.x FTP daemon contains a buffer overflow vulnerability. An attacker can send an overly long string in the CEL command, causing a buffer overflow condition and allowing the attacker to execute arbitrary code.
|
Affected Systems | IBM AIX 4.3.x
|
Attack Scenarios | An attacker sends a suspiciously large amount of data to the FTP server in the CEL command, causing a buffer overflow condition. The attacker can then execute arbitrary code to obtain root privileges.
|
Ease of Attack | Simple. Exploits exist.
|
Corrective Action | Install the patch provided by IBM. See http://www-1.ibm.com/services/continuity/recover1.nsf/MSS/ERS-SVA-E01-1999.004.1/$file/sva004.txt for an advisory and information about obtaining the patch.
