1Panel: Improper Neutralization of Special Elements used in a Command
CVE-2024-34352 is a high-severity improper neutralization of special elements used in a command vulnerability in 1Panel from 1Panel-dev, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected 1Panel versions: <= v1.10.2-lts. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.33% chance of exploitation within 30 days, higher than 72% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update 1panel to 1.10.3-lts or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
1Panel is an open source Linux server operation and maintenance management panel. Prior to v1.10.3-lts, there are many command injections in the project, and some of them are not well filtered, leading to arbitrary file writes, and ultimately leading to RCEs. The mirror configuration write symbol `>` can be used to achieve arbitrary file writing. This vulnerability is fixed in v1.10.3-lts.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
