**Name of the Vulnerable Software and Affected Versions** Honeywell Experion PKS versions C200, C200E, C300, and ACE controllers **Description** The issue exists due to improper neutralization of special elements. This may allow a remote attacker to execute arbitrary code and cause a denial-of-service condition, potentially through cross-site scripting attacks. **Recommendations** For Honeywell Experion PKS C200, C200E, C300, and ACE controllers, update to a version that properly neutralizes special elements in output to prevent arbitrary code execution and denial-of-service conditions. At the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Honeywell Experion PKS versions C200, C200E, C300, and ACE **Description** The issue is related to unrestricted file uploads, which may allow an attacker to remotely execute arbitrary code and cause a denial-of-service condition. This could potentially enable an attacker to disrupt the system's operation. **Recommendations** For Honeywell Experion PKS versions C200, C200E, C300, and ACE, consider restricting file uploads to prevent remote execution of arbitrary code until a patch is available. As a temporary workaround, restrict access to file upload functionality to minimize the risk of exploitation.
