Official Description

Buffer overflow in RSEds.dll in RSHWare.exe in the EDS Hardware Installation Tool 1.0.5.1 and earlier in Rockwell Automation RSLinx Classic before 2.58 allows user-assisted remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed .eds file.

Technical Analysis

CVE-2011-2530 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
