CVE-2020-4776
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 · uneditedA path traversal vulnerability may impact IBM Curam Social Program Management 7.0.9 and 7.0.10, which could allow a remote attacker to traverse directories on the system. An attacker could send a specially-crafted file path in URL request to view arbitrary files on the system. IBM X-Force ID: 189154.
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 · moderate confidenceA path traversal vulnerability in IBM Curam Social Program Management versions 7.0.9 and 7.0.10 allows remote attackers to access arbitrary files on the system by sending specially-crafted file path sequences (e.g., ../) in URL requests, exploiting insufficient input validation on file path parameters.

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.
-
Identify installed IBM Curam versionLocate the version information in the IBM Curam installation directory, typically found in version manifest files, About dialog, or administrative console. Common locations include installation logs, config files, or the SPM version file.Affected if The installed version matches exactly 7.0.9.0 or 7.0.10.0
-
Confirm web interface is accessibleVerify that the IBM Curam web application is exposed and reachable via HTTP/HTTPS. This typically runs on application servers like WebSphere. Check if the Curam servlets and endpoints are publicly or internally accessible.Affected if The web interface is accessible and the version is 7.0.9.0 or 7.0.10.0
-
Inspect URL parameter handling for path traversal patternsReview web server or application server access logs for requests containing directory traversal sequences such as ../, ../.., or absolute path patterns in URL parameters. Check the configuration of the web application to see how file path parameters are validated.Affected if Requests with traversal patterns are being processed by the application without rejection, and the version is 7.0.9.0 or 7.0.10.0
-
Check for input validation on file path parametersExamine the web application configuration and servlet filters to determine whether input validation is implemented for file path parameters in URL requests. Look for path normalization or whitelist-based validation logic.Affected if No input validation exists for file path parameters and the version is 7.0.9.0 or 7.0.10.0
You are affected if IBM Curam Social Program Management version 7.0.9.0 or 7.0.10.0 is installed and the web interface processes file path parameters without proper validation.

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.
From vendor dataApply vendor-provided patches for IBM Curam Social Program Management. If no patch is immediately available, implement WAF rules or URL filtering to block directory traversal patterns and validate all file path inputs server-side.
