automation-controller: automation-controller-container: automation-controller: notification template password fields can be decrypted by a notification-template administrator by replaying encrypted values across subfields, exposing plaintext Slack, PagerDuty, Twilio, AWS SNS and Grafana credentials

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. Notification template password fields are encrypted with a key derived from the secret key, the object primary key, and the field name, but not the subfield name, and the API returns the full ciphertext of a passwor...

CVE-2023-54356

A flaw was found in Kyverno. The software supports insecure 3DES cipher suites on its TLS endpoints. A remote attacker could exploit this vulnerability, known as the Sweet32 attack, to recover small amounts of plaintext data. This exploitation requires very long-lived TLS connections carrying lar...

CVE-2026-92921

admin3 (versions through 3.0.0 ) stores account passwords using single-round MD5 with only the username as salt and no key derivation function, as seen in its SecurityUtil.java and UserCredential.java source files. Because MD5 is computationally inexpensive, an attacker with database access can r...

Astra Linux – Vulnerability in OpenSSL

There exists a timing-based side channel in the OpenSSL RSA Decryption implementation. This vulnerability could be sufficient for an attacker to recover plaintext across a network in a Bleichenbacher-style attack. To successfully decrypt data, an attacker would need to be able to send a very larg...

Astra Linux – Vulnerability in libgcrypt20

The ElGamal implementation in Libgcrypt before version 1.9.4 allows plaintext recovery. This occurs because, during interaction between two cryptographic libraries, a dangerous combination of elements arises—specifically, the prime number defined by the receiver’s public key, the generator define...

Astra Linux – Vulnerability in mbedtls

A vulnerability was discovered in Mbed TLS 2.x before version 2.28.7, and also in Mbed TLS 3.x before version 3.5.2. There was a timing-related side channel involved in RSA private operations. This side channel could allow a local attacker to recover the plaintext. To exploit this vulnerability,...
