Summary
Non-constant time webhook token comparison in Jenkins GitLab Plugin
Details
GitLab Plugin 1.5.35 and earlier does not use a constant-time comparison when checking whether the provided and expected webhook token are equal.
This could potentially allow attackers to use statistical methods to obtain a valid webhook token.
GitLab Plugin 1.5.36 uses a constant-time comparison when validating the webhook token.

Summary
Pterodactyl vulnerable to 2FA Sniffing
Details
Pterodactyl version 0.7.13 and lower - 2FA Sniffing
Users who have enabled 2FA protections on their account can unintentionally have their account's existence sniffed by malicious users who enter random credentials into the login fields.
Impact
Users who have enabled 2FA protections on their account can unintentionally have their account's existence sniffed by malicious users who enter random credentials into the login fields.
A logical mistake was made when the original code was written that would wait to verify the user's password until they had provided 2FA credentials if it was enabled on their account. However, because of this you could enter a bad password for a known email and determine if the account exists if you got redirected to a 2FA page.

Summary
Timing attack on HMAC signature comparison in Apache Tapestry
Details
The code which checks HMAC in form submissions used String.equals() for comparisons, which results in a timing side channel for the comparison of the HMAC signatures. This could lead to remote code execution if an attacker is able to determine the correct signature for their payload. The comparison should be done with a constant time algorithm instead.

Summary
Non-constant time HMAC comparison
Details
Jenkins 2.218 and earlier, LTS 2.204.1 and earlier does not use a constant-time comparison when checking whether two HMACs are equal. This could potentially allow attackers to use statistical methods to obtain a valid HMAC for an attacker-controlled input value.
Jenkins 2.219, LTS 2.204.2 now uses a constant-time comparison when validating HMACs.

GHSA-FJ9X-F2WX-V38W
Vulnerability from github – Published: 2022-05-24 17:14 – Updated: 2026-06-05 21:31
VLAI
Details
An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by (1) reconstructing the projective coordinate of the result of scalar multiplication by exploiting side channels in the conversion to affine coordinates; (2) using an attack described by Naccache, Smart, and Stern in 2003 to recover a few bits of the ephemeral scalar from those projective coordinates via several measurements; and (3) using a lattice attack to get from there to the long-term ECDSA private key used for the signatures. Typically an attacker would have sufficient access when attacking an SGX enclave and controlling the untrusted OS.

Vulnerability from github – Published: 2023-09-27 15:30 – Updated: 2024-04-04 07:55
VLAI
Details
PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.

Mitigation MIT-46
Architecture and Design
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation MIT-39
Implementation
- Ensure that error messages only contain minimal details that are useful to the intended audience and no one else. The messages need to strike the balance between being too cryptic (which can confuse users) or being too detailed (which may reveal more than intended). The messages should not reveal the methods that were used to determine the error. Attackers can use detailed information to refine or optimize their original attack, thereby increasing their chances of success.
- If errors must be captured in some detail, record them in log messages, but consider what could occur if the log messages can be viewed by attackers. Highly sensitive information such as passwords should never be saved to log files.
- Avoid inconsistent messaging that might accidentally tip off an attacker about internal state, such as whether a user account exists or not.
CAPEC-189: Black Box Reverse Engineering
An adversary discovers the structure, function, and composition of a type of computer software through black box analysis techniques. 'Black Box' methods involve interacting with the software indirectly, in the absence of direct access to the executable object. Such analysis typically involves interacting with the software at the boundaries of where the software interfaces with a larger execution environment, such as input-output vectors, libraries, or APIs. Black Box Reverse Engineering also refers to gathering physical side effects of a hardware device, such as electromagnetic radiation or sounds.
