By sending a crafted HTTP request, an attacker can place files that overwrite system files processed by the root account, leading to arbitrary command execution and privilege escalation to root. This weakness stems from improper input validation, which corresponds to CWE\u2011434, and can compromise confidentiality, integrity, and availability of the system.", "risk_and_exploitability": "The vulnerability carries a high CVSS score of 8.8, indicating severe impact. However, the EPSS score is less than 1% and the vulnerability has not been recorded in the CISA KEV catalog, suggesting exploitation probability remains low at present. If exploited, the attacker can upload files and execute root\u2011level commands, effectively gaining full control over the host. The exploitation path requires remote access to the web interface and valid credentials with video operator privileges, which may be obtained through credential compromise or insider misuse. Detection should focus on anomalous file uploads or unexpected command execution logs."}}}}, "created": "2026-02-05T11:40:11.906525+00:00", "updated": "2026-04-17T23:30:15.920926+00:00", "vendors": ["cisco", "cisco$PRODUCT$meeting_management"]}
