Erlang/OTP 17.0 < 27.3.4.14 / 28.0 < 28.5.0.3 / 29.0 < 29.0.3 Multiple Vulnerabilities

medium Nessus Plugin ID 325890

Language:

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Erlang/OTP installed on the remote host is 17.0 prior to 27.3.4.14, 28.0 prior to 28.5.0.3, or 29.0 prior to 29.0.3. It is, therefore, affected by multiple vulnerabilities:

 - Observable Response Discrepancy vulnerability in Erlang OTP ssh (ssh_sftpd module) allows an authenticated SFTP user to enumerate the existence of files and directories outside the configured root directory.
 (CVE-2026-53422)

 - Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in Erlang OTP ssh (ssh_sftpd module) allows an authenticated SFTP user to render an SFTP channel permanently unresponsive. (CVE-2026-54886)

 - Improper Enforcement of Message Integrity During Transmission in a Communication Channel vulnerability in Erlang/OTP ssl (tls_gen_connection module) allows a network-positioned attacker to inject unauthenticated plaintext that the TLS client application later treats as authenticated server data. (CVE-2026-54891)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Erlang/OTP version 27.3.4.14, 28.5.0.3, or 29.0.3 or later.
