Researchers Warn of Ongoing Attacks Exploiting Critical Zimbra Postjournal Flaw

Researchers Warn of Ongoing Attacks Exploiting Critical Zimbra Postjournal Flaw

Oct 02, 2024 Email Security / Vulnerability
Cybersecurity researchers are warning about active exploitation attempts targeting a newly disclosed security flaw in Synacor's Zimbra Collaboration. Enterprise security firm Proofpoint said it began observing the activity starting September 28, 2024. The attacks seek to exploit CVE-2024-45519 , a severe security flaw in Zimbra's postjournal service that could enable unauthenticated attackers to execute arbitrary commands on affected installations. "The emails spoofing Gmail were sent to bogus addresses in the CC fields in an attempt for Zimbra servers to parse and execute them as commands," Proofpoint said in a series of posts on X. "The addresses contained Base64 strings that are executed with the sh utility." The critical issue was addressed by Zimbra in versions 8.8.15 Patch 46, 9.0.0 Patch 41, 10.0.9, and 10.1.1 released on September 4, 2024. A security researcher named lebr0nli (Alan Li) has been credited with discovering and reporting the short...
Apache Cordova App Harness Targeted in Dependency Confusion Attack

Apache Cordova App Harness Targeted in Dependency Confusion Attack

Apr 23, 2024 Supply Chain Attack / Application Security
Researchers have identified a dependency confusion vulnerability impacting an archived Apache project called Cordova App Harness . Dependency confusion attacks  take place owing to the fact that package managers check the public repositories before private registries, thus allowing a threat actor to publish a malicious package with the same name to a public package repository. This causes the package manager to inadvertently download the fraudulent package from the public repository instead of the intended private repository. If successful, it can have serious consequences, such as infecting all downstream customers that install the package. A May 2023 analysis of npm and PyPI packages stored in cloud environments by enterprise security company Orca  revealed  that nearly 49% of organizations are vulnerable to a dependency confusion attack. While npm and other package managers have since introduced fixes to prioritize the private versions, a...
Sparring in the Cyber Ring: Using Automated Pentesting to Build Resilience

Sparring in the Cyber Ring: Using Automated Pentesting to Build Resilience

Mar 26, 2025Penetration Testing / Vulnerability
"A boxer derives the greatest advantage from his sparring partner…" — Epictetus, 50–135 AD Hands up. Chin tucked. Knees bent. The bell rings, and both boxers meet in the center and circle. Red throws out three jabs, feints a fourth, and—BANG—lands a right hand on Blue down the center. This wasn't Blue's first day and despite his solid defense in front of the mirror, he feels the pressure. But something changed in the ring; the variety of punches, the feints, the intensity – it's nothing like his coach's simulations. Is my defense strong enough to withstand this? He wonders, do I even have a defense? His coach reassures him "If it weren't for all your practice, you wouldn't have defended those first jabs. You've got a defense—now you need to calibrate it. And that happens in the ring." Cybersecurity is no different. You can have your hands up—deploying the right architecture, policies, and security measures—but the smallest gap in your defense could let an attacker land a kn...
