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 · unedited
Perception LiteWeb allows remote attackers to bypass access controls for files via an extra leading / (slash) or leading \ (backslash) in the URL.

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 confidence

Perception LiteWeb contains a path traversal vulnerability in its access control mechanism. Attackers can bypass file access restrictions by prefixing requested file paths with an extra forward slash (/) or backslash (\) in the URL. This allows unauthorized access to sensitive files outside the intended web root or protected directories.

MitigationApply available vendor patches for Perception LiteWeb. If no patch exists, implement URL normalization logic in the web server to strip redundant path separators before performing access control checks, or deploy a web application firewall (WAF) to block requests with malformed path prefixes.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm LiteWeb installation
    Check if Perception LiteWeb is installed on the system by looking for the liteweb.exe or related executable files in the web server directories.
    Affected if LiteWeb is installed and running as the web server
  2. Identify LiteWeb version
    Check the version of the installed LiteWeb server. This can typically be found in the application itself, its binary properties, or any version information file included with the installation.
    Affected if The installed version is exactly 2.5 (the only affected version listed)
  3. Verify access control configuration
    Examine the LiteWeb configuration files to determine if access controls or file restrictions are enabled. Look for settings related to restricted directories, protected files, or access control rules.
    Affected if Access control restrictions are configured and enforced on the web server
  4. Test path traversal bypass
    Send HTTP requests to the LiteWeb server with URLs that prefix file paths with an extra forward slash (/) or backslash (\) to attempt to access files outside the web root. For example: request /../ or \..\ in the URL path.
    Affected if Requests with extra path separators successfully bypass access controls and return files that should be restricted

A system is affected if it runs Perception LiteWeb version 2.5 with access control restrictions enabled, and the path traversal bypass test successfully returns restricted files.

From vendor data
Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply available vendor patches for Perception LiteWeb. If no patch exists, implement URL normalization logic in the web server to strip redundant path separators before performing access control checks, or deploy a web application firewall (WAF) to block requests with malformed path prefixes.
