Francis Provencher has reported a vulnerability in Novell NetWare, which can be exploited by malicious users to potentially compromise a vulnerable system.
The vulnerability is caused due to a boundary error in NWFTPD.nlm when processing FTP commands. This can be exploited to cause a stack-based buffer overflow via specially crafted arguments passed to the MKD, RMD, RNFR, and DELE commands.
Successful exploitation may allow execution of arbitrary code.
The vulnerability is reported in NWFTPD.NLM versions prior to 5.10.01.
Solution: Update NWFTPD.NLM to version 5.10.01.
Provided and/or discovered by: Francis Provencher of Protek Research Lab's, and Nick DeBaggis via ZDI.
