The vulnerability allows a remote user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote administrator can send a specially crafted HTTP request and execute arbitrary code on the target system.


2) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2020-9690)

CWE-ID: CWE-208 - Information Exposure Through Timing Discrepancy

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to the an exploitable timing discrepancy issue. A remote administrator can disclose sensitive information on the target system, leading to signature verification bypass.

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
