Vulnerability from github – Published: 2023-02-15 18:30 – Updated: 2025-03-19 18:30
VLAI
Details
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.

Vulnerability from github – Published: 2026-08-25 03:32 – Updated: 2026-08-25 03:32

Details
The Grav Login plugin (getgrav/grav-plugin-login) before 3.9.1 is vulnerable to email address enumeration. The register() method in classes/Login.php throws a distinct exception (EMAIL_NOT_AVAILABLE) when a submitted email address already belongs to an existing account, while allowing registration to proceed otherwise. Because the registration endpoint has no rate limiting, an attacker can enumerate which email addresses have accounts on the site, one guess per request.

Summary
ZITADEL "ignoring unknown usernames" vulnerability
Details
Impact
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". Due to a implementation change to prevent deadlocks calling the database, the flag would not be correctly respected in all cases and an attacker would gain information if an account exist within ZITADEL, since the error message shows "object not found" instead of the generic error message.
Patches
2.x versions are fixed on >= 2.58.1 2.57.x versions are fixed on >= 2.57.1 2.56.x versions are fixed on >= 2.56.2 2.55.x versions are fixed on >= 2.55.5 2.54.x versions are fixed on >= 2.54.8 2.53.x versions are fixed on >= 2.53.9
ZITADEL recommends upgrading to the latest versions available in due course.
Workarounds
There is no workaround since a patch is already available.

"details": "### Impact\n\nZITADEL 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\u0027t exist and report \"Username or Password invalid\".\nDue to a implementation change to prevent deadlocks calling the database, the flag would not be correctly respected in all cases and an attacker would gain information if an account exist within ZITADEL, since the error message shows \"object not found\" instead of the generic error message.\n\n### Patches\n\n2.x versions are fixed on \u003e= [2.58.1](https://github.com/zitadel/zitadel/releases/tag/v2.58.1)\n2.57.x versions are fixed on \u003e= [2.57.1](https://github.com/zitadel/zitadel/releases/tag/v2.57.1)\n2.56.x versions are fixed on \u003e= [2.56.2](https://github.com/zitadel/zitadel/releases/tag/v2.56.2)\n2.55.x versions are fixed on \u003e= [2.55.5](https://github.com/zitadel/zitadel/releases/tag/v2.55.5)\n2.54.x versions are fixed on \u003e= [2.54.8](https://github.com/zitadel/zitadel/releases/tag/v2.54.8)\n2.53.x versions are fixed on \u003e= [2.53.9](https://github.com/zitadel/zitadel/releases/tag/v2.53.9)\n\nZITADEL recommends upgrading to the latest versions available in due course.\n\n### Workarounds\n\nThere is no workaround since a patch is already available.\n\n### Questions\n\nIf you have any questions or comments about this advisory, please email us at [security@zitadel.com](mailto:security@zitadel.com)",

GHSA-56PM-3VMF-87QJ
Vulnerability from github – Published: 2023-10-30 18:30 – Updated: 2023-11-03 21:30
VLAI
Details
In Package Manager, there is a possible way to determine whether an app is installed, without query permissions, due to side channel information disclosure. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Vulnerability from github – Published: 2022-05-13 01:12 – Updated: 2022-05-13 01:12
VLAI
Details
A Bleichenbacher type side-channel based padding oracle attack was found in the way nettle handles endian conversion of RSA decrypted PKCS#1 v1.5 data. An attacker who is able to run a process on the same physical core as the victim process, could use this flaw extract plaintext or in some cases downgrade any TLS connections to a vulnerable server.

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.
