- CWE-331 - Insufficient Entropy
Summary
An insufficient entropy vulnerability exists in the salt generation functionality of WWBN AVideo dev master commit 15fed957fb. A specially crafted series of HTTP requests can lead to privilege escalation. An attacker can gather system information via HTTP requests and brute force the salt offline, leading to forging a legitimate password recovery code for the admin user.

Summary
WebService::Xero 0.11 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions.
Specifically WebService::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.

Summary
Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as an HMAC session cookie secret by default.
These predictable default secrets can be exploited by an attacker to forge session cookies. An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user’s session.

- CWE-331 - Insufficient Entropy
Summary
An insufficient entropy vulnerability was found in the Openshift Console. In the authorization code type and implicit grant type, the OAuth2 protocol is vulnerable to a Cross-Site Request Forgery (CSRF) attack if the state parameter is used inefficiently. This flaw allows logging into the victim’s current application account using a third-party account without any restrictions.

Mitigation
Phase: Implementation
Description:
- Determine the necessary entropy to adequately provide for randomness and predictability. This can be achieved by increasing the number of bits of objects such as keys and seeds.
CAPEC-59: Session Credential Falsification through Prediction
This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
