The researchers advise Linux users to move to a different collaboaration suite, especially since Microsoft announced plans to stop supporting the app for the platform by December.

For those that can’t move to a different solution immediately, they can create a monitoring rule to discover processes accessing the following directories:

* [Windows] %AppData%\Microsoft\Teams\Cookies
* [Windows] %AppData%\Microsoft\Teams\Local Storage\leveldb
* [macOS] ~/Library/Application Support/Microsoft/Teams/Cookies
* [macOS] ~/Library/Application Support/Microsoft/Teams/Local Storage/leveldb
* [Linux] ~/.config/Microsoft/Microsoft Teams/Cookies
* [Linux] ~/.config/Microsoft/Microsoft Teams/Local Storage/leveldb

BleepingComputer has contacted Microsoft about the company’s plans to release a fix for the issue and will update the article when we get an answer.

Update 9/14/22 – A Microsoft spokesperson sent us the following comment regarding Vectra’s findings:

The technique described does not meet our bar for immediate servicing as it requires an attacker to first gain access to a target network.

We appreciate Vectra Protect’s partnership in identifying and responsibly disclosing this issue and will consider addressing in a future product release. ​Trending: GIFShell attack creates reverse shell using Microsoft Teams GIFs

No confidence in OSCP
https://www.reddit.com/r/Pentesting/comments/xeta12/no_confidence_in_oscp/

I have rooted around 30 machines on PG Practice so far with only about 3 machines without walkthroughs or hints. I have taken tons of notes as i went along but each machine, old or new, i seem to need to look at the walkthroughs again. Enumeration, googling, testing exploits but can’t really move forward most of the time. Exam is scheduled a month from now and i really worried that i wouldnt be able to root even 1 machine. What should i do? I really want to be a pentester but seems frustrated at times because of this submitted by /u/Intelligent-Quiet566 (https://www.reddit.com/user/Intelligent-Quiet566)

CVE-2022-40137: High-Severity BIOS Security Flaw in Lenovo devices

Four additional BIOS-related vulnerabilities have recently been discovered, according to a new security advisory from Lenovo. Attackers can use these flaws to allow information exposure, denial of service, or privilege escalation. The first of the bugs, identified as CVE-2022-40137, affects the WMI SMI Handler function and affects the Lenovo Desktop, Desktop AIO, Smart Edge, Smart Office, ThinkStation, and ThinkSystem models. It could be exploited by an attacker with local access and elevated privileges to execute arbitrary code.

The three problems, identified as CVE-2022-40134, CVE-2022-40135, and CVE-2022-40136, are all related to information leak vulnerabilities that, according to Lenovo, might allow users on vulnerable computers to gain access to read SMM memory.

SMI Set BIOS Password SMI Handler and Smart USB Protection both contain vulnerabilities. In some Lenovo models, SMI Handler and SMI Handler are used to configure platform parameters via WMI. This time, Lenovo addressed four vulnerabilities, with CVE-2022-40137 having the highest priority. Threats to the UEFI (BIOS) system can be very hazardous and covert. Because they are run early in the boot process, before the operating system takes over, they are able to get around practically all security precautions and mitigations higher in the stack that may prevent their OS payloads from being executed. To reduce potential dangers, users of vulnerable devices are strongly advised to upgrade their firmware.
