An issue was discovered in Foxit Reader and PhantomPDF before 9.7.2. It has brute-force attack mishandling because the CAS service lacks a limit on login failures.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Phantompdf Foxitsoftware * 9.7.2 (excluding)
Reader Foxitsoftware * 9.7.2 (excluding)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
