Some vulnerabilities remain unreported for the longest time. The 12-year-old Dell SupportAssist remote code execution (RCE) flaw – which was finally unearthed earlier this year – would be one example.
Others, however, have not only been long since reported and had patches released, but continue to pose a threat to enterprises. A joint advisory from the National Cyber Security Centre (NCSC) and the US Cybersecurity and Infrastructure Security Agency (CISA), published in late July, liste...
Pulse Secure has rushed a fix for a critical zero-day security vulnerability in its Connect Secure VPN devices, which has been exploited by nation-state actors to launch cyberattacks against U.S. defense, finance and government targets, as well as victims in Europe.
Pulse Secure also patched three other security bugs, two of them also critical RCE vulnerabilities.
The zero-day flaw, tracked as CVE-2021-22893, was first disclosed on April 20 and carries the highest possible CVSS sever...
Crucial flaw won't be fixed until next month Now it is F5’s turn to reveal critical security bugs – and the Feds were quick to sound the alarm on these BIG-IP flaws

U.S. government officials have warned that advanced persistent threat actors (APTs) are now leveraging Microsoft’s severe privilege-escalation flaw, dubbed “Zerologon,” to target elections support systems.
Days after Microsoft sounded the alarm that an Iranian nation-state actor was actively exploiting the flaw (CVE-2020-1472), the Cybersecurity Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI) published a joint advisory warning of further attacks.
