CVE-2024-28033
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOS command injection vulnerability exists in WebProxy 1.7.8 and 1.7.9, which may allow a remote unauthenticated attacker to execute an arbitrary OS command with the privilege of the running web server. Note that the developer was unreachable, therefore, users should consider stop using WebProxy 1.7.8 and 1.7.9.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceOS command injection vulnerability in WebProxy versions 1.7.8 and 1.7.9 allows remote unauthenticated attackers to execute arbitrary OS commands with the privileges of the web server process. The vulnerability stems from insufficient input validation in the proxy functionality, enabling an attacker to inject shell metacharacters into parameters that are subsequently passed to system call functions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate WebProxy installationSearch for the WebProxy binary or running process. On Linux, run: ps aux | grep -i webproxy. Also check common installation paths like /usr/bin/webproxy, /usr/local/bin/webproxy, or look for webproxy in your package manager: dpkg -l | grep -i webproxy (Debian) or rpm -qa | grep -i webproxy (RHEL/CentOS)Affected if WebProxy binary or process is found on the system
-
Determine installed versionRun the webproxy binary with version flag: webproxy -v or webproxy --version. If unavailable, check the package version from your package manager output from step 1Affected if Installed version is 1.7.8 or 1.7.9
-
Confirm proxy service is network-exposedCheck if WebProxy is listening on any network port. Run: netstat -tlnp | grep -i webproxy or ss -tlnp | grep -i webproxy. Look for ports typically used by proxy services such as 8080, 3128, or 8888Affected if WebProxy is bound to a network interface (especially 0.0.0.0 or all interfaces)
System is affected if WebProxy version 1.7.8 or 1.7.9 is installed AND the proxy service is actively listening on a network port, allowing remote attackers to inject commands through the proxy parameters.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedSince the developer is unreachable and no patch will be released, organizations should immediately cease using WebProxy 1.7.8 and 1.7.9 and migrate to an actively maintained alternative solution such as nginx, Apache Traffic Server, or Squid.
- Stop using WebProxy 1.7.8 and 1.7.9 immediately as no patch is available
- Identify an alternative proxy solution that is actively maintained and receives security updates
- Plan and execute migration from WebProxy to the chosen alternative solution
- Remove WebProxy 1.7.8 and 1.7.9 from production environments
