Description: In May 2014, the Avast anti-virus forum was hacked and 423k member records were exposed online. The Simple Machines Based forum included usernames, email addresses and password hashes of about 422,959 individuals.
Description: Avast successfully developed a decryptor for the DoNex ransomware family, identifying a flaw that allowed victims to recover their files without charge. Previously known as Muse and DarkRace, DoNex, which emerged in April 2022, targeted individuals and organizations, causing disruptions mainly in the US, Italy, and Belgium. By encrypting files with a ChaCha20 symmetric key and further securing the symmetric file key with RSA-4096 encryption, the ransomware demanded a ransom for file decryption. Avast’s decryptor has been distributed in secrecy since March 2024, in collaboration with law enforcement, to avoid alerting the ransomware authors. The company also provided the public with Indicators of Compromise to help identify and mitigate this security threat.
Description: A malware campaign has been discovered targeting systems using a vulnerable Avast Anti-Rootkit driver. This driver allowed malware to disable security tools and assume control over the system. The compromise affected various security products from multiple companies, with the malware utilizing kernel-level access to terminate security processes. Organizations were advised to instate protections against BYOVD (Bring Your Own Vulnerable Driver) tactics, which use legitimate but compromised drivers to evade detection. Indicators of compromise have been provided to assist in thwarting such attacks, highlighting the importance of protecting systems against kernel-level threats posed by flawed security drivers.
Description: Gen Digital claimed to have been a victim of a cyberattack, and threat actors had taken advantage of the recently discovered MOVEit Transfer vulnerability CVE-2023-34362. The business acknowledged that threat actors had access to employee personal data. Names, residences, dates of birth, and corporate email addresses are among the data that have been exposed. The business informed the concerned third parties as well as the data protection authorities.
Description: The Vermont Office of the Attorney General reported on January 9, 2023, that NortonLifeLock Gen Digital experienced a data breach, where unauthorized third parties likely accessed customer usernames and passwords for accounts created before December 1, 2022. The breach began around December 1, 2022, and potentially exposed customer first names, last names, phone numbers, and mailing addresses. The number of affected individuals is currently unknown.
Description: Gen Digital, previously Symantec Corporation, and NortonLifeLock, alerted its clients to the fact that threat actors had compromised Norton Password Manager accounts through credential-stuffing assaults. The company stated that while none of its systems had been penetrated, the attack may have utilized credentials that came from another source. NortonLifeLock has not yet made public how many customers are affected. Threat actors could have accessed Password Manager accounts and seen information such as first and last names, phone numbers, and mailing addresses. NortonLifeLock has announced the adoption of additional security measures for the affected accounts and reset Norton passwords on those accounts in response to the incident.
Description: Identity theft protection firm LifeLock have exposed customers to additional attacks from ID thieves and phishers. The company just fixed a vulnerability on its site that allowed anyone with a Web browser to index email addresses associated with millions of customer accounts, or to unsubscribe users from all communications from the company.

vLLM is an inference and serving engine for large language models (LLMs). Prior to 0.11.1, vllm has a critical remote code execution vector in a config class named Nemotron_Nano_VL_Config. When vllm loads a model config that contains an auto_map entry, the config class resolves that mapping with get_class_from_dynamic_module(...) and immediately instantiates the returned class. This fetches and executes Python from the remote repository referenced in the auto_map string. Crucially, this happens even when the caller explicitly sets trust_remote_code=False in vllm.transformers_utils.config.get_config. In practice, an attacker can publish a benign-looking frontend repo whose config.json points via auto_map to a separate malicious backend repo; loading the frontend will silently run the backend’s code on the victim host. This vulnerability is fixed in 0.11.1.
fastify-reply-from is a Fastify plugin to forward the current HTTP request to another server. Prior to 12.5.0, by crafting a malicious URL, an attacker could access routes that are not allowed, even though the reply.from is defined for specific routes in @fastify/reply-from. This vulnerability is fixed in 12.5.0.
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 21.0.2, 20.3.15, and 19.2.17, A Stored Cross-Site Scripting (XSS) vulnerability has been identified in the Angular Template Compiler. It occurs because the compiler's internal security schema is incomplete, allowing attackers to bypass Angular's built-in security sanitization. Specifically, the schema fails to classify certain URL-holding attributes (e.g., those that could contain javascript: URLs) as requiring strict URL security, enabling the injection of malicious scripts. This vulnerability is fixed in 21.0.2, 20.3.15, and 19.2.17.
Gin-vue-admin is a backstage management system based on vue and gin. In 2.8.6 and earlier, attackers can delete any file on the server at will, causing damage or unavailability of server resources. Attackers can control the 'FileMd5' parameter to delete any file and folder.
Portkey.ai Gateway is a blazing fast AI Gateway with integrated guardrails. Prior to 1.14.0, the gateway determined the destination baseURL by prioritizing the value in the x-portkey-custom-host request header. The proxy route then appends the client-specified path to perform an external fetch. This can be maliciously used by users for SSRF attacks. This vulnerability is fixed in 1.14.0.
