1. Introduction
Magnoware DataTrack System is affected by an information disclosure vulnerability. This allows attackers to view pages that require authorization by appending a backslash (‘\’) to web requests. This could lead to unauthorized access of sensitive system information, impacting confidentiality. Systems running the Magnoware DataTrack application are likely affected.
2. Technical Explanation
The vulnerability stems from improper input validation in the web server handling of URL paths. Appending a backslash (‘\’) bypasses authorization checks, allowing access to restricted pages. The installed version is also potentially vulnerable to cross-site scripting and directory disclosure. CVE-2010-2079 describes this issue.
- Root cause: Missing input validation on URL paths allows traversal of the file system.
- Exploit mechanism: An attacker appends a backslash (‘\’) to a web request, bypassing authorization controls and accessing unauthorized pages. For example, requesting
http://example.com/page\instead ofhttp://example.com/page. - Scope: Magnoware DataTrack System versions are affected; specific vulnerable versions are not detailed in the provided context.
3. Detection and Assessment
Confirm vulnerability by attempting to access restricted pages with a backslash appended to the URL. Use Nessus or other scanners to identify potentially affected systems.
- Quick checks: Check the installed version of Magnoware DataTrack System via its web interface (if accessible) or system file information.
- Scanning: Nessus vulnerability ID d7656775 can detect this issue, but may not be exhaustive.
- Logs and evidence: Examine web server logs for requests containing backslashes (‘\’) in the URL path.
4. Solution / Remediation Steps
A solution is currently unknown. The following steps outline a general approach for addressing similar vulnerabilities, but may not be directly applicable.
4.1 Preparation
- Stop the web server service to prevent further exploitation during remediation. A roll back plan involves restoring from backup or reverting the system snapshot.
- Changes should be approved by the security team and implemented during a scheduled maintenance window.
4.2 Implementation
- Step 1: Monitor vendor advisories for an official patch or update for Magnoware DataTrack System.
- Step 2: If no patch is available, investigate implementing URL path sanitization within the web server configuration or application code.
- Step 3: Implement strict access controls and least privilege principles to limit potential damage from exploitation.

4.4 Security Practices Relevant to This Vulnerability
Several security practices can help mitigate this type of vulnerability.
- Practice 1: Least privilege – limit user access rights to only what is necessary, reducing the impact if an attacker gains unauthorized access.
- Practice 2: Input validation – sanitize all user-supplied input to prevent malicious data from being processed by the application.
4.5 Automation (Optional)
No automation steps are available at this time due to lack of a known solution.
5. Verification / Validation
- Post-fix check: Attempt to access a restricted page (e.g.,
http://example.com/admin\). The request should be blocked and return an error message. - Re-test: Re-run the initial test by appending a backslash (‘\’) to various web requests and confirm that access is denied.
- Monitoring: Monitor web server logs for failed requests containing backslashes (‘\’) as an indicator of attempted exploitation.
6. Preventive Measures and Monitoring
Implement security baselines and continuous monitoring to prevent similar vulnerabilities.
- Baselines: Update your web server security baseline to include input validation rules and access control configurations.
- Pipelines: Integrate Static Application Security Testing (SAST) into your CI/CD pipeline to identify potential vulnerabilities in application code.
- Asset and patch process: Establish a regular patch management cycle for all software, including web servers and applications.
7. Risks, Side Effects, and Roll Back
Implementing URL path sanitization or access control changes may introduce compatibility issues with existing application functionality.
- Risk or side effect 1: Incorrectly configured input validation rules could block legitimate user requests.
- Risk or side effect 2: Changes to access controls may disrupt existing workflows.
- Roll back: Restore the Magnoware DataTrack System application and its database from backup if any issues occur. Revert any changes made to web server configurations.
