CVE-2021-22900– A vulnerability allowed multiple unrestricted uploads in Pulse Connect Secure before 9.1R11.4 that could lead to an authenticated administrator to perform a file write via a maliciously crafted archive upload in the administrator web interface.CVE-2021-22899 – A command injection vulnerability exists in Pulse Connect Secure before 9.1R11.4 allows a remote authenticated attacker to perform remote code execution via Windows Resource Profiles Feature.CVE-2021-22894 – A buffer overflow vulnerability exists in Pulse Connect Secure before 9.1R11.4 allows a remote authenticated attacker to execute arbitrary code as the root user via maliciously crafted meeting room.This vulnerability has been exploited in the wild. CVE-2021-22893 – Pulse Connect Secure 9.0R3/9.1R1 and higher is vulnerable to an authentication bypass vulnerability exposed by the Windows File Share Browser and Pulse Secure Collaboration features of Pulse Connect Secure that can allow an unauthenticated user to perform remote arbitrary code execution on the Pulse Connect Secure gateway.The new breach comes on the heels of two other major security incidents that CISA has helped respond to over the past four months.A group of vulnerabilities with CVSS scores ranging from 7.2 (High) to 10 (Critical) have been reported:

“We are making significant investments to enhance our overall cyber security infrastructure, including evolving standards of code development and conducting a full code integrity review.” “A secure computing environment is more important each and every day to how we work and live, as threats evolve and emerge,” PCS Chief Security Officer Phil Richards wrote in the blog post. The company also published a blog post detailing more about the vulnerabilities, noting that it was working with CISA, FireEye and other leading industry experts to investigate the hacking incident. “The PCS team has provided remediation guidance to these customers directly.” “The Pulse Connect Secure (PCS) team is in contact with a limited number of customers who have experienced evidence of exploit behavior on their PCS appliances,” the spokesperson told The Hill in a statement.

Defense Industrial Base and European organizations and stressed that it was in the "early stages" of full attribution.Ī spokesperson for Ivanti told The Hill Tuesday that the patch for the vulnerabilities would be released in May and that only a “limited number” of customers had been compromised. Mandiant found that the hacking group had targeted organizations in the U.S. The alert was released after cybersecurity group FireEye’s Mandiant Solutions, which is working with Ivanti to respond to the hacking incident, published a blog post attributing some of the hacking activity to a Chinese state-sponsored hacking group and another Chinese advanced persistent threat group. "This determination is based on the current exploitation of these vulnerabilities by threat actors in external network environments, the likelihood of the vulnerabilities being exploited, the prevalence of the affected software in the federal enterprise, the high potential for a compromise of agency information systems, and the potential impact of a successful compromise."

"CISA has determined that this exploitation of Pulse Connect Secure products poses an unacceptable risk to Federal Civilian Executive Branch agencies and requires emergency action," the agency wrote in the directive.

#PULSE SECURE EXPLOIT UPDATE#
In addition, CISA put out an emergency directive Tuesday night requiring all federal agencies to assess how many Pulse Connect Secure products they and third-party organizations used and to update these products by April 23. The agency wrote that Ivanti was developing a patch for these vulnerabilities and that it “strongly encouraged” all organizations using these products to update to the newest version and investigate for signs of compromise.
