PowerPanel business: Relative Path Traversal

CVE-2024-33615 is a high-severity relative path traversal vulnerability in PowerPanel business from CyberPower, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 4.9.0 as the first without the flaw, so updating PowerPanel business to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.71% chance of exploitation within 30 days, higher than 54% of scored CVEs.

Official description

A specially crafted Zip file containing path traversal characters can be imported to the CyberPower PowerPanel server, which allows file writing to the server outside the intended scope, and could allow an attacker to achieve remote code execution.

The underlying weakness: Relative Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.

How developers prevent this class of flaw

  • Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
