PoC Exploit | Breaking Cybersecurity News | The Hacker News

A malicious actor released a fake proof-of-concept (PoC) exploit for a recently disclosed WinRAR vulnerability on GitHub with an aim to infect users who downloaded the code with Venom RAT malware. "The fake PoC meant to exploit this WinRAR vulnerability was based on a publicly available PoC script that exploited a SQL injection vulnerability in an application called GeoServer, which is tracked as  CVE-2023-25157 ," Palo Alto Networks Unit 42 researcher Robert Falcone  said . While  bogus PoCs  have become a  well-documented gambit  for targeting the  research community , the cybersecurity firm suspected that the threat actors are opportunistically targeting other crooks who may be adopting the latest vulnerabilities into their arsenal. whalersplonk, the  GitHub account  that hosted the repository, is no longer accessible. The PoC is said to have been committed on August 21, 2023, four days after the vulnerability was publicly announced. CVE-2023-40477 relates to an  imp

A proof-of-concept (PoC) exploit code has been made available for the recently disclosed critical security flaw affecting Fortinet FortiOS, FortiProxy, and FortiSwitchManager, making it imperative that users move quickly to apply the patches. "FortiOS exposes a management web portal that allows a user to configure the system," Horizon3.ai researcher James Horseman  said . "Additionally, a user can SSH into the system which exposes a locked down CLI interface." The issue, tracked as  CVE-2022-40684  (CVSS score: 9.6), concerns an  authentication bypass  vulnerability that could allow a remote attacker to perform malicious operations on the administrative interface via specially crafted HTTP(S) requests. A successful exploitation of the shortcoming is tantamount to granting complete access "to do just about anything" on the affected system, including altering network configurations, adding malicious users, and intercepting network traffic. That said,
