Cobalt Strike Delivered Through Fake Proof-of-Concept Code

FortiGuard Labs is aware of a report that a Cobalt Strike beacon was attempted to be delivered through a couple of fake Proof-of-Concept (POC) codes hosted on GitHub. The files pretend to be POCs for CVE-2022-26809 and CVE-2022-24500. They have already been removed from GitHub.Why is this Significant?This is significant because the attack targeted researchers, pen testers and infosec teams in organizations to deliver Cobalt Strike beacons, which will most likely be used to deliver malware such as ransomware.What is CVE-2022-26809?CVE-2022-26809 is a remote procedure call runtime remote code execution vulnerability that affects wide variety of Windows OS that includes Windows 7, 8, 10, 11, Windows Server 2008, 2012, 2016, 2019 and 2022. Assigned a CVSS score of 9.8, successfully exploiting the vulnerability allows an attacker to execute remote code with high privileges on a vulnerable system, leading to a full compromise. The vulnerability was patched as part of Patch Tuesday April 2022..

CVE-2021-32989

When a non-existent resource is requested, the LCDS LAquis SCADA application (version 4.3.1.1011 and prior) returns error messages which may allow reflected cross-site scripting.

CVE-2021-32997

The affected Baker Hughes Bentley Nevada products (3500 System 1 6.x, Part No. 3060/00 versions 6.98 and prior, 3500 System 1, Part No. 3071/xx & 3072/xx versions 21.1 HF1 and prior, 3500 Rack Configuration, Part No. 129133-01 versions 6.4 and prior, and 3500/22M Firmware, Part No. 288055-01 versions 5.05 and prior) utilize a weak encryption algorithm for storage and transmission of sensitive data, which may allow an attacker to more easily obtain credentials used for access.

CVE-2021-35487

Nokia Broadcast Message Center through 11.1.0 allows an authenticated user to perform a Boolean Blind SQL Injection attack on the endpoint /owui/block/send-receive-updates (for the Manage Alerts page) via the extIdentifier HTTP POST parameter. This allows an attacker to obtain the database user, database name, and database version information, and potentially database data.

CVE-2021-32966

Philips Interoperability Solution XDS versions 2.5 through 3.11 and 2018-1 through 2021-1 are vulnerable to clear text transmission of sensitive information when configured to use LDAP via TLS and where the domain controller returns LDAP referrals, which may allow an attacker to remotely read LDAP system credentials.

CVE-2021-3597

A flaw was found in undertow. The HTTP2SourceChannel fails to write the final frame under some circumstances, resulting in a denial of service. The highest threat from this vulnerability is availability. This flaw affects Undertow versions prior to 2.0.35.SP1, prior to 2.2.6.SP1, prior to 2.2.7.SP1, prior to 2.0.36.SP1, prior to 2.2.9.Final and prior to 2.0.39.Final.
