https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 Two Ivanti Connect Secure and Policy Secure zero-days, an authentication bypass (CVE-2023-46805) and a command injection (CVE-2024-21887), were chained for unauthenticated remote code execution on internet-facing VPN gateways. Volexity found them in the wild in December 2023 and disclosed them on 2024-01-10. A third bug, an SSRF in the SAML component (CVE-2024-21893), was exploited later in January. CISA issued Emergency Directive 24-01 and then ordered federal agencies to disconnect all Ivanti Connect Secure and Policy Secure appliances. Added to the CISA KEV catalog on 2024-01-10, 2024-01-31. CISA lists known use in ransomware campaigns. en Wed, 31 Jan 2024 00:00:00 GMT https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-31-f3cb5e3b Wed, 31 Jan 2024 00:00:00 GMT critical <p><a href="https://nvd.nist.gov/vuln/detail/CVE-2024-21893">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-31-89c16d58 Wed, 31 Jan 2024 00:00:00 GMT critical <p><a href="https://www.cisa.gov/known-exploited-vulnerabilities-catalog">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-31-7b405805 Wed, 31 Jan 2024 00:00:00 GMT critical <p><a href="https://www.cisa.gov/news-events/directives/supplemental-direction-v1-ed-24-01-mitigate-ivanti-connect-secure-and-ivanti-policy-secure">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-19-74db6c1f Fri, 19 Jan 2024 00:00:00 GMT critical <p><a href="https://www.cisa.gov/news-events/directives/ed-24-01-mitigate-ivanti-connect-secure-and-ivanti-policy-secure-vulnerabilities">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-12-21ddf221 Fri, 12 Jan 2024 00:00:00 GMT critical <p><a href="https://nvd.nist.gov/vuln/detail/CVE-2023-46805">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-12-7929bed7 Fri, 12 Jan 2024 00:00:00 GMT critical <p><a href="https://nvd.nist.gov/vuln/detail/CVE-2024-21887">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-10-4f185c19 Wed, 10 Jan 2024 00:00:00 GMT critical <p><a href="https://www.cisa.gov/known-exploited-vulnerabilities-catalog">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-10-d7c89827 Wed, 10 Jan 2024 00:00:00 GMT critical <p><a href="https://www.cisa.gov/known-exploited-vulnerabilities-catalog">Source</a></p> https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893 https://pwn.watch/i/ivanti-connect-secure-zero-days-cve-2023-46805-cve-2024-21887-21893#2024-01-10-6d8ffebb Wed, 10 Jan 2024 00:00:00 GMT critical <p><a href="https://www.volexity.com/blog/2024/01/10/active-exploitation-of-two-zero-day-vulnerabilities-in-ivanti-connect-secure-vpn/">Source</a></p>
