Information Disclosure

ruby is vulnerable to information disclosure. It was found that Ruby did not reinitialize the PRNG pseudorandom number generator after forking a child process. This could eventually lead to the PRNG returning the same result twice. An attacker keeping track of the values returned by one child...

Information Leakage

Ruby is vulnerable to information leakage. The attack is possible due to a flaw in the Ruby SecureRandom module. When using the SecureRandom.randombytes class, the PRNG state was not modified after forking a child process. This could eventually lead to SecureRandom.randombytes returning the same...

Epignosis eFront LMS Password Reset authentication bypass vulnerability

Summary A predictable seed vulnerability eixsts in the password reset functionality of Epignosis EfrontPro 5.2.21. By predicting the seed it is possible to generate the correct password reset 1-time token. An attacker can visit the password reset supplying the password reset token to reset the...

Security Bulletin: Multiple vulnerabilities in IBM HTTP Server affects Netezza Performance Portal

Summary IBM HTTP Server is used by IBM Netezza Performance Portal. IBM Netezza Performance Portal has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2016-0702 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a side-channel attack agains...

COMpfun successor Reductor infects files on the fly to compromise TLS traffic

In April 2019, we discovered new malware that compromises encrypted web communications in an impressive way. Analysis of the malware allowed us to confirm that the operators have some control over the target's network channel and could replace legitimate installers with infected ones on the fly...

Cryptographically Weak PRNG

Overview All versions of generator-jhipster-kotlin use a Cryptographically Weak PRNG that may lead to account takeover. The package uses a cryptographically insecure method to generate password reset links, which allows an attacker to guess password reset links and takeover accounts. Recommendati...

CVE-2019-10754

Multiple classes used within Apereo CAS before release 6.1.0-RC5 makes use of apache commons-lang3 RandomStringUtils for token and ID generation which makes them predictable due to RandomStringUtils PRNG's algorithm not being cryptographically strong...

Critical severity vulnerability that affects generator-jhipster

Account takeover and privilege escalation is possible in applications generated by generator-jhipster before 6.3.0. This is due to a vulnerability in the generated java classes: CWE-338: Use of Cryptographically Weak Pseudo-Random Number Generator PRNG Generated applications must be manually...
