Palo Alto Networks is warning {that a} vital zero-day vulnerability on Subsequent-Era Firewalls (NGFW) administration interfaces, presently tracked as ‘PAN-SA-2024-0015,’ is actively being exploited in assaults.
The flaw was initially disclosed on November 8, 2024, with Palo Alto Networks warning clients to limit entry to their next-generation firewalls due to a “potential” distant code execution (RCE) vulnerability impacting them.
No indicators of exploitation have been detected at the moment, however now, one week later, the scenario has modified.
“Palo Alto Networks has noticed menace exercise exploiting an unauthenticated distant command execution vulnerability in opposition to a restricted variety of firewall administration interfaces that are uncovered to the Web,” warns an replace on the advisory web page.
“Presently, we imagine gadgets whose entry to the Administration Interface is just not secured as per our really helpful greatest apply deployment pointers are at elevated danger,” warns the seller in the identical bulletin.
The vulnerability, rated with a CVSS v4.0 rating of 9.3 (“vital”), is remotely exploitable and requires no authentication or person interplay.
As soon as an internet-exposed interface is detected, the attacker can ship a specifically crafted request to realize unauthorized management over the firewall, probably enabling them to change guidelines, redirect or intercept community site visitors, and switch off safety protections.
Sadly, the seller doesn’t have ample info to formulate a helpful checklist of indicators of compromise presently, however instructed the next mitigation steps:
- Configure entry to the firewall administration interface so it’s only accessible from trusted inner IP addresses.
- Block all web entry to the administration interface to stop exploitation.
- Place the administration interface behind a secured community or VPN to make sure entry is managed and authenticated.
- Evaluation and implement the safety pointers discovered right here.
Regardless of the harmful RCE bug being found per week in the past, Palo Alto Networks has not but made safety updates obtainable to impacted purchasers.
“Presently, securing entry to the administration interface is the very best really helpful motion,” says Palo Alto Networks.
“As we examine the menace exercise, we’re getting ready to launch fixes and menace prevention signatures as early as attainable.”
Menace monitoring platform The Shadowserver Basis reported earlier at present that it sees roughly 8,700 uncovered interfaces.
Menace researcher Yutaka Sejiyama carried out his personal scans on Shodan and instructed BleepingComputer that he noticed 11,180 IP addresses uncovered on-line related to the Palo Alto administration interface.
“As you understand, the outcomes from Shodan will not be real-time info. Nonetheless, throughout my investigation three days in the past, I confirmed that 11,180 of those IPs have been really on-line,” Sejiyama instructed BleepingComputer.
In accordance with Shodan, a lot of the gadgets are positioned in the USA, adopted by India, Mexica, Thailand, and Indonesia.

To make sure that you’ve got utilized the mitigations correctly, go to the Property part of the Palo Alto Networks Buyer Assist Portal to discover a checklist of gadgets with Web-facing administration interfaces, and search for gadgets tagged with ‘PAN-SA-2025-0015.’
If none confirmed up, the scan didn’t detect any internet-exposed administration interfaces. In the event that they do, admins ought to use the steps talked about to safe gadgets.
