ProxyNotShell threats are far from over. Nearly 60,000 Exchange servers were found vulnerable to CVE-2022-41082, one of the two ProxyNotShell flaws. Nonetheless, the number of flawed servers has plummeted (not-so-significantly) as compared to mid-December’s count. Speaking of security holes, Qualcomm issued patches to fix five bugs that also concern some Lenovo models. Some Lenovo models are affected by the bugs in question that could be abused to expose sensitive data and cause memory corruption.

The malware landscape also has added a new threat, as disclosed by the ASEC team. Researchers stumbled across a new shell script compiler (shc)-based malware downloader that could bring along XMRing miner on compromised systems.

Top Vulnerabilities Reported in the Last 24 Hours

Thousands of Exchange servers are vulnerable
The infamous RCE vulnerability, CVE-2022-41082, aka ProxyNotShell bug, is back in headlines as researchers unveiled that approximately 60,000 Exchange servers are yet to be patched against the threat. Successful exploitation of the bug allows adversaries to escalate privileges and gain arbitrary code-writing access on compromised servers.

Multiple bugs in Qualcomm chips
Researchers disclosed five bugs in Qualcomm chipsets that also affect Lenovo ThinkPad X13s laptops. The bugs, identified as CVE-2022-40516 through CVE-2022-40520, are memory corruption and information disclosure (due to buffer over-read in Core). Lenovo has released BIOS updates to patch the bugs.
