Ivanti Pulse Connect Secure Code Execution Vulnerability
Ivanti - Pulse Connect Secure · Listed in the CISA KEV since 2021-11-03. This indicates confirmed attacks in production environments.
Required action: Apply updates per vendor instructions.
CVE-2020-8260
HighCVSS 7.2KEVSummary
A vulnerability in the Pulse Connect Secure < 9.1R9 admin web interface could allow an authenticated attacker to perform an arbitrary code execution using uncontrolled gzip extraction.
Risk Assessment
An authenticated attacker could execute arbitrary code on the device, potentially leading to full system compromise. However, valid administrative credentials are required.
Recommendation
Update Pulse Connect Secure to version 9.1R9 or later. Restricting access to the admin interface is also recommended.
Other vulnerabilities in Pulse Connect Secure
See all- CVE-2017-11196High
Pulse Connect Secure 8.3R1 has a CSRF vulnerability in logout.cgi. The logout function of the admin panel is not protected by any CSRF tokens, allowing an attacker to log out a user by tricking them into visiting a malicious web page.
- CVE-2017-11193High
Pulse Connect Secure 8.3R1 has a CSRF vulnerability in the diag.cgi file, which allows commands like ping, traceroute, and nslookup to be executed. The lack of CSRF protections enables an attacker to run these commands against any IP if they can trick an admin into visiting their malicious page.
- CVE-2016-4786High
Pulse Connect Secure (PCS) versions 8.2 before 8.2r1, 8.1 before 8.1r3, 8.0 before 8.0r11, and 7.4 before 7.4r13.4 allow remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.
- CVE-2021-22900HighActively exploited
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.
