Detailsinfo

A vulnerability was found in IBM Personal Communications and classified as very critical. Affected by this issue is an unknown part in the library pcspref.dll of the file pcsws.exe. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in pcspref.dll in pcsws.exe in IBM Personal Communications 5.9.x before 5.9.8 and 6.0.x before 6.0.4 might allow remote attackers to execute arbitrary code via a long profile string in a WorkStation (aka .ws) file.

The weakness was published 03/02/2012 by Metasploit with stratsec (Website). The advisory is available at exploit-db.com. This vulnerability is handled as CVE-2012-0201 since 12/14/2011. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details as well as a public exploit are known. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 08/26/2025). It is expected to see the exploit prices for this product increasing in the near future.

A public exploit has been developed by Metasploit and been published even before and not after the advisory. The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $25k-$100k.

Upgrading to version 6.0.3.0 eliminates this vulnerability.
