Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
1) Server-Side Request Forgery (SSRF)
EUVDB-ID: #VU60709
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2022-22993
CWE-ID:
CWE-918 - Server-Side Request Forgery (SSRF)
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input within the cgi_api endpoint. A remote user on the local network can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
