Summary
Duplicate Advisory: Uncaught Exception processing HTTP Headers in SurrealDB
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-m24x-r6q3-2vp9. This link is maintained to preserve external references.

Original Description

SurrealDB versions before 1.1.0 fail to properly parse the ID, DB, and NS headers in HTTP REST API requests containing special characters. Unauthenticated attackers can send crafted HTTP requests with malformed header values to trigger an uncaught exception that crashes the server.

GHSA-FFCV-V6PW-QHRP

Vulnerability from github – Published: 2024-10-08 22:18 – Updated: 2024-10-31 19:31
VLAI
Summary
Denial of Service in TYPO3 Bookmark Toolbar
Details

Problem

Due to insufficient input validation, manipulated data saved in the bookmark toolbar of the backend user interface causes a general error state, blocking further access to the interface. Exploiting this vulnerability requires an administrator-level backend user account.

Solution

Update to TYPO3 versions 10.4.46 ELTS, 11.5.40 LTS, 12.4.21 LTS, 13.3.1 that fix the problem described.

Credits

Thanks to Hendrik Eichner who reported this issue and to TYPO3 core & security team members Oliver Hader and Benjamin Franzke who fixed the issue.

Vulnerability from github – Published: 2025-02-05 18:34 – Updated: 2025-02-05 18:34
VLAI
Details

A vulnerability in the SNMP subsystem of Cisco IOS Software, Cisco IOS XE Software, and Cisco IOS XR Software could allow an authenticated, remote attacker to cause a DoS condition on an affected device.

This vulnerability is due to improper error handling when parsing SNMP requests. An attacker could exploit this vulnerability by sending a crafted SNMP request to an affected device. For Cisco IOS and IOS XE Software, a successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition. For Cisco IOS XR Software, a successful exploit could allow the attacker to cause the SNMP process to restart, resulting in an interrupted SNMP response from an affected device. Devices that are running Cisco IOS XR Software will not reload.  This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMP v2c or earlier, the attacker must know a valid read-write or read-only SNMP community string for the affected system. To exploit this vulnerability through SNMP v3, the attacker must have valid SNMP user credentials for the affected system.

A vulnerability in Multer versions >= 1.4.4-lts.1, < 2.0.2 allows an attacker to trigger a Denial of Service (DoS) by sending a malformed request. This request causes an unhandled exception, leading to a crash of the process.

Patches

Users should upgrade to 2.0.2

Workarounds

None

Vulnerability from github – Published: 2025-04-15 15:30 – Updated: 2025-04-15 15:30
VLAI
Details

The vulnerability allows any authenticated user to cause the PeerTube server to stop functioning in a persistent manner.  If user import is enabled (which is the default setting), any registered user can upload an archive for importing. The code uses the yauzl library for reading the archive. If the yauzl library encounters a filename that is considered illegal, it raises an exception that is uncaught by PeerTube, leading to a crash which repeats infinitely on startup.

Summary
Denial of Service in sequelize
Details

Versions of sequelize prior to 4.44.4 are vulnerable to Denial of Service (DoS). The SQLite dialect fails to catch a TypeError exception for the results variable. The results value may be undefined and trigger the error on a .map call. This may allow attackers to submit malicious input that forces the exception and crashes the Node process.

The following proof-of-concept crashes the Node process:

const Sequelize = require('sequelize');

const sequelize = new Sequelize({
    dialect: 'sqlite',
    storage: 'database.sqlite'
});

const TypeError = sequelize.define('TypeError', {
    name: Sequelize.STRING,
});

TypeError.sync({force: true}).then(() => {
    return TypeError.create({name: "SELECT tbl_name FROM sqlite_master"});
});

Recommendation

Upgrade to version 4.44.4 or later.

Vulnerability from github – Published: 2026-08-22 00:31 – Updated: 2026-08-27 21:31
VLAI
Details

Tie::Hash::Regex versions before 2.0.0 for Perl will throw an exception on unparseable lookup keys.

The FETCH, EXISTS and DELETE methods throw an exception when on malformed regular expressions.

Each method falls back to a regex match when the key is not already stored in the hash, compiling the caller's key with a bare qr// and no eval guard. A key that is not a valid regular expression pattern, such as a single unmatched bracket, dies.

An application that looks up externally supplied strings in a tied hash will die on an invalid key.
