4.4.2- Upgrade moodle/moodle to this version or later
Description
A flaw was found in moodle. The cURL wrapper in Moodle strips HTTPAUTH and USERPWD headers during emulated redirects, but retains other original request headers, so HTTP authorization header information could be unintentionally sent in requests to redirect URLs.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-319: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How to prevent it
- Architecture and Design: Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- Implementation: When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- Implementation: When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
- Testing: Use tools and techniques that require manual (human) analysis, such as penetration testing, threat modeling, and interactive tools that allow the tester to record and modify an active session. These may be more effective than strictly automated techniques. This is especially the case with weaknesses that are related to design and business rules.
- Operation: Configure servers to use encrypted channels for communication, which may include SSL or other secure protocols.
