CVE-2021-37393 describes a stored Cross-Site Scripting (XSS) vulnerability in RPCMS v1.8 and earlier, where the "nickname" variable is not properly sanitized. An authenticated attacker can inject XSS payloads via the "update password" function, which then executes when other users view articles published by the compromised account. This vulnerability has a CVSS score of 5.4 (Medium), indicating a network-based attack with low complexity, requiring user interaction, and resulting in low confidentiality and integrity impacts. The EPSS score is low, suggesting a minimal likelihood of exploitation in the wild. Currently, there is no evidence of active exploitation, and no public exploit code is available on platforms like Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are also minimal.
