Exploitation vector: Network

Exploit availability: Yes

Vulnerable software:
IP

Vendor: indutny

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input within the isPublic() function when handling certain IP addresses, such as 127.1, 01200034567, 012.1.2.3, 000:0:0000::01, and ::fFFf:127.0.0.1. A remote attacker 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.

Note, the vulnerability exists due to incomplete fix for #VU86944 (CVE-2023-42282).

Mitigation
