CVE-2025-31124 2025-04-01 N/A N/A
Zitadel is open-source identity infrastructure software. ZITADEL administrators can enable a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report "Username or Password invalid". While the setting was correctly respected during the login flow, the user's username was normalized leading to a disclosure of the user's existence. This vulnerability is fixed in 2.71.6, 2.70.8, 2.69.9, 2.68.9, 2.67.13, 2.66.16, 2.65.7, 2.64.6, and 2.63.9.
CVE-2025-30344 1 Openslides 1 Openslides 2025-03-27 N/A 3.7 LOW
An issue was discovered in OpenSlides before 4.2.5. During login at the /system/auth/login/ endpoint, the system's response times differ depending on whether a user exists in the system. The timing discrepancy stems from the omitted hashing of the password (e.g., more than 100 milliseconds).
CVE-2024-0436 1 Mintplexlabs 1 Anythingllm 2025-03-27 N/A 5.9 MEDIUM
Theoretically, it would be possible for an attacker to brute-force the password for an instance in single-user password protection mode via a timing attack given the linear nature of the `!==` used for comparison. The risk is minified by the additional overhead of the request, which varies in a non-constant nature making the attack less reliable to execute
CVE-2024-5690 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2025-03-26 N/A 4.3 MEDIUM
By monitoring the time certain operations take, an attacker could have guessed which external protocol handlers were functional on a user's system. This vulnerability affects Firefox < 127, Firefox ESR < 115.12, and Thunderbird < 115.12.
CVE-2024-2408 2 Fedoraproject, Php 2 Fedora, Php 2025-03-21 N/A 5.9 MEDIUM
The openssl_private_decrypt function in PHP, when using PKCS1 padding (OPENSSL_PKCS1_PADDING, which is the default), is vulnerable to the Marvin Attack unless it is used with an OpenSSL version that includes the changes from this pull request: https://github.com/openssl/openssl/pull/13817 (rsa_pkcs1_implicit_rejection). These changes are part of OpenSSL 3.2 and have also been backported to stable versions of various Linux distributions, as well as to the PHP builds provided for Windows since the previous release. All distributors and builders should ensure that this version is used to prevent PHP from being vulnerable. PHP Windows builds for the versions 8.1.29, 8.2.20 and 8.3.8 and above include OpenSSL patches that fix the vulnerability.
CVE-2022-4304 2 Openssl, Stormshield 4 Openssl, Endpoint Security, Sslvpn and 1 more 2025-03-20 N/A 5.9 MEDIUM
A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE. For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.
CVE-2023-0361 5 Debian, Fedoraproject, Gnu and 2 more 7 Debian Linux, Fedora, Gnutls and 4 more 2025-03-19 N/A 7.4 HIGH
A timing side-channel in the handling of RSA ClientKeyExchange messages was discovered in GnuTLS. This side-channel can be sufficient to recover the key encrypted in the RSA ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption the attacker would need to send a large amount of specially crafted messages to the vulnerable server. By recovering the secret from the ClientKeyExchange message, the attacker would be able to decrypt the application data exchanged over that connection.
CVE-2020-12413 1 Mozilla 2 Firefox, Firefox Esr 2025-03-19 N/A 5.9 MEDIUM
The Raccoon attack is a timing attack on DHE ciphersuites inherit in the TLS specification. To mitigate this vulnerability, Firefox disabled support for DHE ciphersuites.

CVE-2023-1998 2 Debian, Linux 2 Debian Linux, Linux Kernel 2025-02-13 N/A 5.6 MEDIUM
The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects.
