Microsoft has shared details of a now-patched flaw in Apple macOS that could be abused by threat actors with root access to bypass security enforcements and perform arbitrary actions on affected devices. "The most straight-forward implication of a SIP bypass is that an attacker can create files that are protected by SIP and therefore undeletable by ordinary means," Microsoft researchers Jonathan Bar Or, Michael Pearse, and Anurag Bohra said.
Apple has recently addressed a vulnerability that lets attackers with root privileges bypass System Integrity Protection to install "Undeletable" malware and access the victim's private data by circumventing Transparency, Consent, and Control security checks.

D-Link has fixed two critical-severity vulnerabilities in its D-View 8 network management suite that could allow remote attackers to bypass authentication and execute arbitrary code.D-View is a network management suite developed by the Taiwanese networking solutions vendor D-Link, used by businesses of all sizes for monitoring performance, controlling device configurations, creating network maps, and generally making network management and administration more efficient and less time-consuming.
CISA warned today of a security vulnerability affecting Samsung devices used in attacks to bypass Android address space layout randomization protection. The exposed info can be used by local attackers with high privileges to conduct an ASLR bypass which could enable the exploitation of memory-management issues.
Microsoft fixed a security vulnerability this week that could be used by remote attackers to bypass recent patches for a critical Outlook zero-day security flaw abused in the wild. "All Windows versions are affected by the vulnerability. As a result, all Outlook client versions on Windows are exploitable," Barnea explained.
Cybersecurity researchers have found a way to exploit a recently disclosed critical flaw in PaperCut servers in a manner that bypasses all current detections.
