CVE-2021-27600

Status: ModifiedMedium (5.4)—

SAP Manufacturing Execution (System Rules), versions - 15.1, 15.2, 15.3, 15.4, allows an authorized attacker to embed malicious code into HTTP parameter and send it to the server because SAP Manufacturing Execution (System Rules) tab does not sufficiently encode some parameters, resulting in Stored Cross-Site Scripting (XSS) vulnerability. The malicious code can be used for different purposes. e.g., information can be read, modified, and sent to the attacker. However, availability of the server cannot be impacted.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
