@campuscodi Kudos to @h4sh for assigning the CVE to the actively exploited CrushFTP zero-day: https://infosec.exchange/@h4sh/112316550866303546

According to his analysis and patch diffing, the CVSSv3 score for CVE-2024-4040 is 7.7 HIGH: Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N

Did some patch diffing on the new #crushFTP bug, and it does look like the bug has 2 components and at least one of them need some form of authentication to exploit (need creation of something).
After the first stage, the reading of the file outside of VFS sandbox might not need authentication. I am not sure.

Shoutout to @h4sh for getting a CVE ID assigned to this actively exploited zero-day CrushFTP vulnerability: CVE-2024-4040 (reported by Simon Garrelou, of Airbus CERT). https://www.cve.org/CVERecord?id=CVE-2024-4040

VFS Sandbox Escape in CrushFTP in all versions before 10.7.1 and 11.1.0 on all platforms allows remote attackers with low privileges to read files from the filesystem outside of VFS Sandbox.

Microsoft reported that APT28 (Fancy Bear, Forest Blizzard) used a custom tool to elevate privileges and steal credentials in compromised networks. This GooseEgg tool leveraged CVE-2022-38028 (7.8 high, disclosed 11 October 2022 by Microsoft; Windows Print Spooler Elevation of Privilege Vulnerability) as a zero-day since at least June 2020 (possibly as early as April 2019) which was 2 years 4 months. APT28 is publicly attributed to Russian General Staff Main Intelligence Directorate (GRU).

Palo Alto Networks released additional details about CVE-2024-3400: the fact that it is a combination of two bugs in PAN-OS; how an attacker was exploiting it; how disabling telemetry initially worked; and how they fixed it. The timeline from discovery to remediation encompasses the whole blog post. Overall a comprehensive after-action review from a company that notified the public almost immediately of an exploited zero-day. 🔗https://www.paloaltonetworks.com/blog/2024/04/more-on-the-pan-os-cve/

In case you missed it, Palo Alto Networks updated their security advisory in terms of product and mitigation guidance, exploit status, and PAN-OS fix availability: 🔗 https://security.paloaltonetworks.com/CVE-2024-3400

• Exploitation status: Proof of concepts for this vulnerability have been publicly disclosed by third parties.
• Workarounds and mitigations: In earlier versions of this advisory, disabling device telemetry was listed as a secondary mitigation action. Disabling device telemetry is no longer an effective mitigation. Device telemetry does not need to be enabled for PAN-OS firewalls to be exposed to attacks related to this vulnerability.
• Solution:
  • - 10.2.6-h3 (Released 4/16/24)
  • - 11.0.3-h10 (Released 4/16/24)
  • - 11.0.2-h4 (Released 4/16/24)

It should come as no surprise that Palo Alto Networks did not release hotfixes* for affected versions of PAN-OS 10.2, PAN-OS 11.0, and PAN-OS 11 by the self-imposed deadline of Sunday 14 April 2024 like they estimated in their security advisory. 48 hours to develop/test/release is a tight delivery window with the whole infosec community breathing down their necks.

@TheDustinChilds of Zero Day Initiative alleges that CVE-2024-29988 (8.8 high) was also exploited in the wild and should be marked an exploited zero-day 🔗 https://www.zerodayinitiative.com/blog/2024/4/9/the-april-2024-security-updates-review

This is an odd one, as a ZDI threat researcher found this vulnerability being in the wild, although Microsoft currently doesn’t list this as exploited. I would treat this as in the wild until Microsoft clarifies. The bug itself acts much like CVE-2024-21412 – it bypasses the Mark of the Web (MotW) feature and allows malware to execute on a target system. Threat actors are sending exploits in a zipped file to evade EDR/NDR detection and then using this bug (and others) to bypass MotW.
