Description

This security bulletin contains information about 2 vulnerabilities.


1) Expected behavior violation (CVE-ID: CVE-2025-46712)

CWE-ID: CWE-440 - Expected Behavior Violation

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


The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to OTP SSH fails to enforce strict kex handshake hardening measures by allowing optional messages to be exchanged. A remote attacker can perform a Man-in-the-Middle attack and inject these messages in a connection during the handshake.


2) Path traversal (CVE-ID: CVE-2025-4748)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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


The vulnerability allows a remote attacker to write arbitrary files to the system.

The vulnerability exists due to improper validation of .zip archives in the Erlang/OTP standard-library ZIP routines "zip:unzip/1,2" and "zip:extract/1,2". A remote attacker can pass a specially crafted .zip archive to the application and write files to arbitrary locations on the system.
