HPE LoadRunner < 12.50 mchan.dll Packet Handling Invalid Memory Access DoS

high Nessus Plugin ID 97552
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


An application installed on the remote Windows host is affected by a denial of service vulnerability.


The version of HP LoadRunner installed on the remote Windows host is prior to 12.50 patch 3. It is, therefore, affected by a denial of service vulnerability in the mchan.dll library due to improper parsing of malformed packets. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to crash the service.


Upgrade to HP LoadRunner version 12.50 patch 3 or later.
