A high-severity security bug affecting several Netgear small office/home office routers could allow remote code execution via a man-in-the-middle attack. From there, attackers can serve up a malicious database update that triggers RCE, which can be created by downloading and modifying a legitimate Netgear database update, researchers said.

Apache OpenOffice, one of the most popular open-source office productivity software suites, sports a RCE vulnerability that could be triggered via a specially crafted document. CVE-2021-33035 was discovered by researcher Eugene Lim via fuzzing and source code review of Apache OpenOffice.

On September 2021 Patch Tuesday, Microsoft has fixed 66 CVE-numbered vulnerabilities in a wide variety of its solutions. Of these, the most crucial to address is CVE-2021-40444, the remote code execution MSHTML vulnerability actively exploited by attackers via malicious MS Office documents.

Both Microsoft and federal cybersecurity officials are urging organizations to use mitigations to combat a zero-day remote control execution vulnerability in Windows that allows attackers to craft malicious Microsoft Office documents. Microsoft has not revealed much about the MSHTML bug, tracked as CVE-2021-40444, beyond that it is "Aware of targeted attacks that attempt to exploit this vulnerability by using specially-crafted Microsoft Office documents," according to an advisory released Tuesday.

Attackers are exploiting CVE-2021-40444, a zero-day remote code execution vulnerability in MSHTML, to compromise Windows/Office users in "a limited number of targeted attacks," Microsoft has warned on Tuesday. CVE-2021-40444 is a set of logical flaws that can be leveraged by remote, unauthenticated attackers to execute code on the target system.

Taiwan-based NAS maker Synology has revealed that recently disclosed remote code execution and denial-of-service OpenSSL vulnerabilities impact some of its products. "Multiple vulnerabilities allow remote attackers to conduct denial-of-service attack or execute arbitrary code via a susceptible version of Synology DiskStation Manager, Synology Router Manager, VPN Plus Server or VPN Server," the company explains in a security advisory published earlier today.

In a security advisory published on Wednesday, Cisco said that a critical vulnerability in Universal Plug-and-Play service of multiple small business VPN routers will not be patched because the devices have reached end-of-life. "The Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers have entered the end-of-life process."

A day after releasing Patch Tuesday updates, Microsoft acknowledged yet another remote code execution vulnerability in the Windows Print Spooler component, adding that it's working to remediate the issue in an upcoming security update. Tracked as CVE-2021-36958, the unpatched flaw is the latest to join a list of bugs collectively known as PrintNightmare that have plagued the printer service and come to light in recent months.

A day after releasing Patch Tuesday updates, Microsoft acknowledged yet another remote code execution vulnerability in the Windows Print Spooler component, adding that it's working to remediate the issue in an upcoming security update. "A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations," the company said in its out-of-band bulletin, echoing the vulnerability details for CVE-2021-34481.

In a Thursday security advisory update, Cisco revealed that a remote code execution vulnerability in the Adaptive Security Device Manager Launcher disclosed last month is a zero-day bug that has yet to receive a security update. Cisco ADSM is a firewall appliance manager that provides a web interface for managing Cisco Adaptive Security Appliance firewalls and AnyConnect Secure Mobility clients.
