  • SSA-594373SSA-594373: Cross-Site-Scripting (XSS) Vulnerability in SINEMA Server V142023-10-10csaf · siemens_psirtDE

    SINEMA Server V14 improperly sanitizes certain SNMP configuration data retrieved from monitored devices. An attacker with access to a monitored device could perform a stored cross-site scripting (XSS) attack that may lead to arbitrary code execution with SYSTEM privileges on the application server. Siemens recommends to migrate to its successor product SINEC NMS V2.0 or later. Siemens recommends to apply specific countermeasures for products where updates are not, or not yet available.
