Deeper analysisAI
CVE-2020-36914 is a sensitive information disclosure vulnerability affecting QiHang Media Web Digital Signage version 3.0.9. The flaw arises from the transmission of user authentication credentials via cleartext cookies, which exposes these credentials to potential interception by unauthorized parties. This issue aligns with CWE-319 (Cleartext Transmission of Sensitive Information) and carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with no requirements for privileges or user interaction.
Remote attackers can exploit this vulnerability over the network with low attack complexity. By conducting man-in-the-middle (MITM) attacks, they can intercept the cleartext cookies containing authentication credentials during transmission, capture them, and potentially misuse them for unauthorized access or further compromise of the system.
