Breaking into network devices in a way that can be used to extract login credential is an important strategy in this secret conflict. A big part of the espionage is getting hold of login credentials of those that have access to interesting secret information. State sponsored cyber-attacks are often more about espionage than about monetary gain with the exception of sabotage against an enemy state. Interested parties can also find technical details and detections there. In their blogpost they discuss 4 variants. According to Mandiant, the malware and its variants are “applied as modifications to legitimate Pulse Secure files to bypass or log credentials in the authentication flows that exist within the legitimate Pulse Secure shared object libdsplibs.so”. It has posted an elaborate analysis of the related malware, which they have dubbed SlowPulse. Threat analysisįireEye’s Mandiant was involved in the research into these vulnerabilities.

These modified scripts on the Pulse Secure system are reported to have allowed the malware to survive software updates and factory resets. They have also observed threat actors deploying modified Pulse Connect Secure files and scripts in order to maintain persistence. Very likely in order to perform lateral movement within compromised organizations’ environments. The identified threat actors were found to be harvesting account credentials.

The workaround also disables the Windows File Share Browser that allows users to browse network file shares. Reportedly, the workaround disables Pulse Collaboration, a feature that allows users to schedule and hold online meetings between both Connect Secure users and non-Connect Secure users. More details can be found in the company’s Security Advisory 44784.
#WHAT IS PULSE SECURE PATCH#
Mitigation requires a workaroundĪccording to Pulse Secure, until the patch is available CVE-2021-22893 can be mitigated by importing a workaround file. There is no patch for it yet (it is expected to be patched in early May), so system administrators will need to mitigate for the problem for now, rather than simply fixing it. This vulnerability has a critical CVSS score and poses a significant risk to your deployment. includes an authentication by-pass vulnerability that can allow an unauthenticated user to perform remote arbitrary file execution on the Pulse Connect Secure gateway.
#WHAT IS PULSE SECURE CODE#
The new vulnerability (CVE-2021-22893) is a Remote Code Execution (RCE) vulnerability with a CVSS score of 10-the maximum-and a Critical rating. The obvious advice here is to review the Pulse advisories for these vulnerabilities and follow the recommended guidance, which includes changing all passwords in the environments that are impacted.

Its goal is to make it easier to share data across separate vulnerability capabilities (tools, databases, and services). Publicly disclosed computer security flaws are listed in the Common Vulnerabilities and Exposures (CVE) database. But there is also a very serious new issue that it says impacts a very limited number of customers. Most of the problems discovered by Pulse Secure and Mandiant involve three vulnerabilities that were patched in 20. PCS provides Virtual Private Network (VPN) facilities to businesses, which use them to prevent unauthorized access to their networks and services.Ĭybersecurity sleuths Mandiant report that they are tracking “12 malware families associated with the exploitation of Pulse Secure VPN devices” operated by groups using a set of related techniques to bypass both single and multi-factor authentication. Pulse Secure has alerted customers to the existence of an exploitable chain of attack against its Pulse Connect Secure (PCS) appliances.
