Cisco has addressed severe vulnerabilities in the Cisco Nexus Dashboard data center management solution that can let remote attackers execute commands and perform actions with root or Administrator privileges. "A successful exploit could allow the attacker to perform actions with Administrator privileges on an affected device," Cisco explains.
New research into the inner workings of the stealthy BPFdoor malware for Linux and Solaris reveals that the threat actor behind it leveraged an old vulnerability to achieve persistence on targeted systems. Cybersecurity company CrowdStrike has observed a threat actor that focused mainly on targeting Linux and Solaris systems using the custom-built BPFDoor implant on telecommunications providers to steal personal user information.
Two of them, rated critical and high severity, can be exploited by attackers to run commands with root privileges or to escape the guest virtual machine and fully compromise NFVIS hosts. CVE-2022-20777 is caused by insufficient guest restrictions and allows authenticated attackers to escape the guest VM and gain root-level access to the host in low complexity attacks without requiring user interaction.
Microsoft has unearthed two security vulnerabilities in the networkd-dispatcher daemon that may be exploited by attackers to gain root on many Linux endpoints, allowing them to deploy backdoors, malware, ransomware, or perform other malicious actions. CVE-2022-29799 is a directory traversal bug; CVE-2022-29800 is a time-of-check-time-of-use race condition that could allow an attacker to replace scripts that networkd-dispatcher believes to be owned by root to ones that are not.
A new set of vulnerabilities collectively tracked as Nimbuspwn could let local attackers escalate privileges on Linux systems to deploy malware ranging from backdoors to ransomware. Security researchers at Microsoft disclosed the issues in a report today noting that they can be chained together to achieve root privileges on a vulnerable system.
If you go off-market, things can get much more dangerous, not least because there are many unofficial Android app stores out there where pretty much anything goes, including some app repositories that deliberately pitch themselves as a handy place to get at software that Google "Doesn't want you to have". As an aside, you might think that no one would deliberately seek out apps that clearly wouldn't be permitted on Google Play, or that have already been rejected by Google.
Western Digital has fixed a critical severity vulnerability that enabled attackers to gain remote code execution with root privileges on unpatched My Cloud OS 5 devices. This flaw is an out-of-bounds heap read/write in the Samba vfs fruit VFS module.

A newly disclosed security flaw in the Linux kernel could be leveraged by a local adversary to gain elevated privileges on vulnerable systems to execute arbitrary code, escape containers, or induce a kernel panic. Tracked as CVE-2022-25636, the vulnerability impacts Linux kernel versions 5.4 through 5.6.10 and is a result of a heap out-of-bounds write in the netfilter subcomponent in the kernel.
Mozilla fixes Firefox zero-days exploited in the wildMozilla has released an out-of-band security update for Firefox, Firefox Focus, and Thunderbird, fixing two critical vulnerabilities exploited by attackers in the wild. Easily exploitable Linux bug gives root access to attackersAn easily exploitable vulnerability in the Linux kernel can be used by local unprivileged users to gain root privileges on vulnerable systems by taking advantage of already public exploits.
