CVE-2023-48795 5.9 - Medium - December 18, 2023

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

Improper Validation of Integrity Check Value

In Erlang/OTP before 23.3.4.15

CVE-2022-37026 9.8 - Critical - September 21, 2022

In Erlang/OTP before 23.3.4.15, 24.x before 24.3.4.2, and 25.x before 25.0.2, there is a Client Authentication Bypass in certain client-certification situations for SSL, TLS, and DTLS.

An issue was discovered in Erlang/OTP before 23.2.2

CVE-2020-35733 7.5 - High - January 15, 2021

An issue was discovered in Erlang/OTP before 23.2.2. The ssl application 10.2 accepts and trusts an invalid X.509 certificate chain to a trusted root Certification Authority.

Improper Certificate Validation

Erlang/OTP 22.3.x before 22.3.4.6 and 23.x before 23.1 allows Directory Traversal

CVE-2020-25623 7.5 - High - October 02, 2020

Erlang/OTP 22.3.x before 22.3.4.6 and 23.x before 23.1 allows Directory Traversal. An attacker can send a crafted HTTP request to read arbitrary files, if httpd in the inets application is used.

Directory traversal

Rebar3 versions 3.0.0-beta.3 to 3.13.2 are vulnerable to OS command injection

CVE-2020-13802 9.8 - Critical - September 02, 2020

Rebar3 versions 3.0.0-beta.3 to 3.13.2 are vulnerable to OS command injection via URL parameter of dependency specification.

Erlang/OTP Rebar3 version 3.7.0 through 3.7.5 contains a Signing oracle vulnerability in Package registry verification

CVE-2019-1000014 8.8 - High - February 04, 2019

Erlang/OTP Rebar3 version 3.7.0 through 3.7.5 contains a Signing oracle vulnerability in Package registry verification that can result in Package modifications not detected, allowing code execution. This attack appears to be exploitable via Victim fetches packages from malicious/compromised mirror. This vulnerability appears to have been fixed in 3.8.0.

Improper Input Validation

Erlang/OTP before 18.0-rc1 does not properly check CBC padding bytes when terminating connections, which makes it easier for man-in-the-middle attackers to obtain cleartext data

CVE-2015-2774 5.9 - Medium - April 07, 2016

Erlang/OTP before 18.0-rc1 does not properly check CBC padding bytes when terminating connections, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a variant of CVE-2014-3566 (aka POODLE).

Information Disclosure

The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time

CVE-2011-0766 - May 31, 2011

The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time, which makes it easier for remote attackers to guess DSA host and SSH session keys.

Cryptographic Issues

CVE-2009-0130 - January 15, 2009

lib/crypto/c_src/crypto_drv.c in erlang does not properly check the return value from the OpenSSL DSA_do_verify function, which might allow remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature, a similar vulnerability to CVE-2008-5077. NOTE: a package maintainer disputes this issue, reporting that there is a proper check within the only code that uses the applicable part of crypto_drv.c, and thus "this report is invalid.
