Detailsinfo

A vulnerability, which was classified as very critical, has been found in Mitsubishi-automation Mitsubishi MX Component 3 (Automation Software). This issue affects an unknown function in the library ActUWzd.dll of the component ActiveX Control. 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. The summary by CVE is:

Multiple buffer overflows in ActUWzd.dll 1.0.0.1 in Mitsubishi MX Component 3, as distributed in Citect CitectFacilities 7.10 and CitectScada 7.10r1, allow remote attackers to execute arbitrary code via a long string, as demonstrated by a long WzTitle property value to a certain ActiveX control.

The weakness was released 04/19/2013 (Website). The advisory is shared at exploit-db.com. The identification of this vulnerability is CVE-2013-3075 since 04/15/2013. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 06/29/2025).

A public exploit has been developed by Dr_IDE and been published even before and not after the advisory. The exploit is available at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 25 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at Exploit-DB (24886), OSVDB (91661†) and Vulnerability Center (SBV-39998†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
