45k Jenkins servers exposed to RCE attacks using public exploits
2024-01-29 22:06

Researchers found roughly 45,000 Jenkins instances exposed online that are vulnerable to CVE-2023-23897, a critical remote code execution flaw for which multiple public proof-of-concept exploits are in circulation. Depending on the instance's configuration, attackers could decrypt stored secrets, delete items from Jenkins servers, and download Java heap dumps.

Using GoAnywhere MFT for file transfers? Patch now – an exploit's out for a critical bug
2024-01-24 15:04

Horizon3's exploit takes advantage of age-old path traversal weaknesses in Tomcat-based applications where requests to vulnerable endpoints that contain /.;/ allow attackers to access forbidden pages, such as the admin account creation page in GoAnywhere MFT. If remote attackers exploit the same path traversal technique when submitting the form to create a new admin user, the account will be created, giving the bad guys admin privileges. Zach Hanley, chief attack engineer at Horizon3, said the clearest indicator of compromise would be noticing any new additions to the Admin Users group in the GoAnywhere MFT admin portal.

Chinese hackers exploit VMware bug as zero-day for two years
2024-01-19 16:32

A Chinese hacking group has been exploiting a critical vCenter Server vulnerability as a zero-day since at least late 2021. In the next stage, they exploited the CVE-2023-20867 VMware Tools authentication bypass flaw to escalate privileges, harvest files, and exfiltrate them from guest VMs. While, until now, Mandiant didn't know how the attackers gained privileged access to victims' vCenter servers, the link was made evident in late 2023 by a VMware vmdird service crash minutes before the backdoors' deployment closely matching CVE-2023-34048 exploitation.
