merbinr/cve-2024-44623Details about the Blind RCE issue(SPX-GC) in SPX-GC
In SPX-GC 1.3.0v and below versions, user-controlled input was passed in the exec function of the child_process module without any sanitization, leading to unauthenticated blind remote code execution.
In /routes/routes-api.js, user input received from file param and passed into exec function of child_process leads to unauthenticated blind RCE
Blind Remote Code Execution (RCE) in web applications occurs when an attacker can execute arbitrary code on a server without immediate feedback or direct knowledge of the results. This vulnerability often arises from improper user input handling and can be exploited through mechanisms like command execution. References:
SPX-GC <= 1.3.0v
Fixed in 31c96893a193428a3a11499ed0e165125f9bbe23 commit, The changes were added to the master branch, so the new build and installation from that branch are not vulnerable. The fix has not yet been published as a release on GitHub.
