CVSS v3 5.6
ATTENTION: Low skill level to exploit.
Vendor: Schneider Electric
Vulnerability: Memory Corruption
Schneider Electric reports that the vulnerability affects the following VAMPSET setting and configuration software products:
- VAMPSET, versions prior to v2.2.189
Successful exploitation of this vulnerability could allow a local attacker to cause the software to enter a denial-of-service condition. The Windows operating system remains operational through the attack.
Schneider Electric has updated the VAMPSET tool in order to recognize malformed setting files. A new version of firmware with the fix for this vulnerability is available for download at the following location:
