Title: Microsoft Visual SourceSafe Client-Side Access Control Weakness
Severity: MODERATE
Description:
Microsoft Visual SourceSafe is software to manage development projects in any programming language.
Microsoft Visual SourceSafe performs validation of permissions for access control for projects on the client side, instead of on the server side. This poses a security threat because a malicious client user may potentially circumvent these security measures to gain unauthorized access to protected files within a project. The only way to restrict access on the server side is to set NTFS permissions, but these permissions must reportedly be applied to an entire project and not individual project files or folders.
If an attacker can exploit this weakness, it will be possible to gain unauthorized access to restricted files within projects that the attacker has access to. As a consequence, it may be possible for a malicious user to view or modify sensitive data in project files. This has the potential to violate security policy for development projects.
Affected Products:
- Microsoft Visual SourceSafe 6.0.0
