Other critical vulnerabilities patched are found in GDI+, HEVC Video Extensions, Microsoft DTV-DVD Video Decoder, and Microsoft Edge. Anyone with an existing installation will need to re-deploy their cluster and use Azure CNI instead of the default Kubernetes.”

This is also requires more than just a patch to fix. “This could allow an attacker to laterally steal the identities that are associated with different pods. When an identity is assigned to a pod, the pod can access to the Azure Instance Metadata Service (IMDS) endpoint and get a token of that identity,” he explained.
“This vulnerability exists in the way that the Azure Active Directory (AAD) pod identity allows users to assign identities to pods in Kubernetes clusters. This sounds pretty bad at first glance, but Microsoft has taken the decision to remove detailed descriptions from the release, leaving us with little context,” Breen pointed out.Īllan Liska, Senior Security Architect at Recorded Future, noted that “while these vulnerabilities are considered critical, and it is concerning that so many vulnerabilities around the same component were released simultaneously, two previous vulnerabilities in RPC Runtime, CVE-2019-1409 and CVE-2018-8514, were not widely exploited.”Ĭhilds has also singled out CVE-2021-1677, an Azure Active Directory Pod vulnerability that may allow identity spoofing, as worthy of special mention (though classed only as “important” by Microsoft.

“CVE-2020-1660 is listed as a remote code execution via the network with a CVSS of 8.8. Though details about it and PoC exploit code have been publicly released by Trend Micro ZDI, it is still not exploited by attackers, but it’s possible it will be soon.Īmong the critical flaws fixed on this January 2021 Patch Tuesday by Microsoft are five Remote Procedure Call runtime RCEs (CVE-2021-1658, CVE-2021-1660, CVE-2021-1666, CVE-2021-1667 and CVE-2021-1673). However, if your systems are not connected to the Internet, you’ll need to manually apply the patch,” Trend Micro Zero Day Initiative’s Dustin Childs commented.Īnother fixed bug of note is CVE-2021-1648, an elevation of privilege vulnerability in the Microsoft splwow64 service. “This bug in the Microsoft Malware Protection Engine may already be patched on your system as the engine auto-updates as needed. Luckily for everyone, patching in this instance is uncomplicated. If there’s any indication that this vulnerability has been exploited on your networks, ensure you look for lateral movement – don’t just focus on the affected device.” In fact, it could be as simple as sending a file the user doesn’t need to interact with anything, as Defender will access it as soon as it is placed onto the system. “Depending on the vector, which is not identified in the update, this could be trivial to exploit.

Because it must be able to scan all the files and processes on your system, Defender has some of the highest permissions available, so if you can run code in this context, you’ll gain full access to the system,” noted Kevin Breen, Director of Cyber Threat Research at Immersive Labs.
“A remote code execution vulnerability in MS Defender is bad news. One of the latter – a zero-day RCE ( CVE-2021-1647) affecting Microsoft Defender antivirus – is being exploited in the wild, but Microsoft didn’t reveal more about these attacks. Microsoft has plugged 83 security holes, 10 of which are critical. Mozilla has fixed a critical vulnerability affecting Thunderbird.SAP has released 10 security notes and updated 7 previously released ones.Adobe has delivered security updates for a variety of products.Microsoft has plugged 83 CVEs, including a Microsoft Defender zero-day.
