**Name of the Vulnerable Software and Affected Versions**
Schneider Electric Quantum versions 140NOE77111, 140NOE77101, and 140NWM10000
Schneider Electric M340 versions BMXNOC0401, BMXNOE0100x, and BMXNOE011xx

**Description**
A cross-site request forgery (CSRF) issue allows remote attackers to hijack the authentication of arbitrary users for requests that execute commands. This can be achieved by modifying HTTP credentials. The vulnerability can also be exploited by an attacker to launch a script in the context of the current user's security using a specially crafted website.
**Recommendations**
For Schneider Electric Quantum versions 140NOE77111, 140NOE77101, and 140NWM10000, update the firmware to prevent CSRF attacks.
For Schneider Electric M340 versions BMXNOC0401, BMXNOE0100x, and BMXNOE011xx, restrict access to the web interface until a patch is available.
For Schneider Electric Premium versions TSXETY4103, TSXETY5103, and TSXWMY100, consider disabling the web server functionality as a temporary workaround until a fix is provided.
As a general mitigation measure, restrict access to the vulnerable PLC modules to minimize the risk of exploitation.
