VAR-201601-0059
Vulnerability from variot - Updated: 2023-12-18 14:05Westermo WeOS before 4.19.0 uses the same SSL private key across different customers' installations, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by leveraging knowledge of a key. WestermoIndustrialSwitches is an industrial Ethernet switch from Westermo, Sweden. A security vulnerability exists in WestermoIndustrialswitches that allows remote attackers to exploit the vulnerability to perform man-in-the-middle attacks without unauthorized access to the device. Westermo Industrial switches are prone to a hard-coded certificate key vulnerability. Successful exploits will allow attackers to read and modify traffic that is intercepted and decrypted. Versions prior to Note- WeOS 4.19.0 are vulnerable
