DRUPAL-CONTRIB-2020-012

This module enables you to build forms and surveys in Drupal. The module doesn't sufficiently validate data submitted into Webform Signature element during webform submission creation. This allows a malicious user to generate and extract HMAC hashes for arbitrary data. Such HMAC hashes are used...

GOG GalaxyClientService Privilege Escalation

This module will send arbitrary filepaths to the GOG GalaxyClientService, which will be executed with SYSTEM privileges verified on GOG Galaxy Client v1.2.62 and v2.0.12; prior versions are also likely affected. Module Options msf use exploit/windows/local/gog/galaxyclientserviceprivesc msf...

The vulnerability of the implementation of the HMAC-SHA-256 mechanism in the GnuTLS cryptographic library allows a perpetrator to carry out an “Lucky 13” attack and a attack that recovers the plaintext.

The vulnerability of the HMAC-SHA-256 mechanism implemented in the GnuTLS cryptographic library is related to errors in the implementation of the cryptographic algorithm. Exploiting this vulnerability allows a malicious actor to perform both a “Lucky 13” attack and an attack that recovers the...

Authentication Bypass

java is vulnerable to authentication bypass. A flaw was found in the way the XML Digital Signature implementation in the JRE handled HMAC-based XML signatures. An attacker could use this flaw to create a crafted signature that could allow them to bypass authentication, or trick a user, applet, or...

Authentication Bypass

net-snmp is vulnerable to authentication bypass. The vulnerability exists as a flaw was found in the way Net-SNMP checked an SNMPv3 packet's Keyed-Hash Message Authentication Code HMAC. An attacker could use this flaw to spoof an authenticated SNMPv3 packet...

CVE-2019-10706

CVE-2020-2102

CVE-2020-2102 affects Jenkins 2.218 and earlier, and LTS 2.204.1 and earlier, where the HMAC validation used a non-constant-time comparison. This can enable a timing-side-channel attack to infer a correct HMAC value for attacker-controlled input. The issue is addressed in Jenkins 2.219 and LTS 2....
