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/

Bleeping Computer: GreyNoise and ShadowServer Foundation are reporting active exploitation of CVE-2024-3400 (10.0 critical, disclosed 12 April 2024 by Palo Alto Networks as an exploited zero-day, OS Command Injection Vulnerability in GlobalProtect Gateway, added to CISA KEV Catalog, has Proof of Concept). The good news is that all hotfixes for vulnerable versions of PAN-OS are now released. 🔗 https://www.bleepingcomputer.com/news/security/22-500-palo-alto-firewalls-possibly-vulnerable-to-ongoing-attacks/

#CVE_2024_3400 #PaloAltoNetworks #activeexploitation #eitw #kev

Zscaler observed exploitation of the Palo Alto Networks PAN-OS command injection zero-day vulnerability CVE-2024-3400 following the release of the PoC exploit code. Zscaler provides an attack flow diagram, and a technical analysis of the Upstyle backdoor and its layers. IOC provided. 🔗 https://www.zscaler.com/blogs/security-research/look-cve-2024-3400-activity-and-upstyle-backdoor-technical-analysis

TrustedSec CTO Justin Elze shared CVE-2024-3400 exploit in the wild on Twitter yesterday, reports that 149.28.194.95 was attempting to exploit CVE-2024-3400

#CVE_2024_3400 #PaloAltoNetworks #zeroday #activeexploitation #eitw #kev #KnownExploitedVulnerabilitiesCatalog #vulnerability #ProofofConcept #threatintel #IOC

The #golang `gorilla/sessions` directory traversal and file (over)write is now being tracked as GO-2024-2730: https://go-review.googlesource.com/c/vulndb/+/579655

This issue was (co)-discovered as part of watchTowr's analysis of the Palo Alto Networks RCE (#CVE_2024_3400), but is entirely separate, and affects a wide range of Go-based web services.

https://github.com/golang/vulndb/issues/2730

If you use gorilla/sessions with the FilesystemStore, please switch to the CookieStore instead until a patch is available.

Okay so the folks who said the LLM-generated "PoC" repos for #CVE_2024_3400 were just claiming the space were dead-on. This repo, which was fake, is now using the known exploit. I expect the others have done the same.

So the lesson here is that we have a PoC ParkingCrew.

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)
  • - 11.1.0-h3 (Released 4/16/24)

Rapid7 vient de publier l'analyse d'exploitation de la vuln CVE-2024-3400 dans les firewalls Palo avec GlobalProtect activé.

(description de l'enchainement d'exploitation avec diffing du patch par snapshots d'un PAN-OS monté en VM)

"Rapid7’s analysis of this vulnerability has identified that the exploit is in fact an exploit chain, consisting of two distinct vulnerabilities: an arbitrary file creation vulnerability in the GlobalProtect web server, for which no discrete CVE has been assigned, and a command injection vulnerability in the device telemetry feature, designated as CVE-2024-3400. If device telemetry is disabled, it is still possible to leverage the file creation vulnerability; at time of writing, however, Rapid7 has not identified an alternative way to leverage the file creation vulnerability for successful exploitation.

Our analysis also found that when device telemetry is enabled, a device certificate must be installed for device telemetry to successfully transmit telemetry data back to Palo Alto Networks. This transmission of data functionality is where the command injection vulnerability lies, and in our testing, the command injection vulnerability could not be triggered without a valid device certificate installed. We observed that transmission of telemetry data only occurs once an hour, per the vendor documentation."

watchTowr may have successfully replicated CVE-2024-3400 (10.0 critical, disclosed 12 April 2024 by Palo Alto Networks as an exploited zero-day, CWE-77: Command Injection; OS Command Injection Vulnerability in GlobalProtect Gateway, added to CISA KEV Catalog).

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.

EDIT: A hotfix is now available for select affected versions of PAN-OS: https://security.paloaltonetworks.com/CVE-2024-3400

@barrybadrinath @jerry I follow the tags #PatchTuesday and #zeroday to see what if anything I haven’t covered already. I also spell out the CVE ID with underscores like #CVE_2024_3400 because I’ve made too many mistakes when it’s squished together. Then I periodically check https://cvecrowd.com and the CVE trends on Twitter to see what’s trending. Shoutout to @kpwn

Shout to all the cats on my timeline that posted about #CVE_2024_3400 like @tychotithonus. Had preventative controls in place by the time I was finishing coffee.

À mon avis - that's an effective social network.
