Musste ich die access.log doch noch mal aus #Crowdsec rausnehmen, sonst würden die ganzen Friendica-Instanzen im laufe des Tages geblockt werden. Ist ungünstig für die Federation, würde ich mal sagen ;)

How to protect your systems:
Patch: Patch your FortiWeb instance if it is publicly exposed; otherwise, remove outside access to the affected admin panel.
Preemptive blocking: Use Crowdsec CTI to block IPs exploiting CVE-2025-25257 https://app.crowdsec.net/cti?q=cves%3A%22CVE-2025-25257%22&page=1
Stay proactive: Install the Crowdsec Web Application Firewall to stay ahead of exploit attempts, with 100+ virtual patching rules available. https://doc.crowdsec.net/docs/next/appsec/intro

Trend analysis:
CrowdSec detected the first in-the-wild exploitation of this vulnerability on July 11th, shortly after we rolled out detection rules. Using our wayback tools, we were able to establish that there were no exploitation attempts before July 11th, confirming once again that public exploits are a key driver of vulnerability weaponization.
For CVE-2025-25257, CrowdSec has observed about 40 distinct IPs producing about 500 attack events in total. Most of these attacks occurred on Friday, July 11th, the day the exploit was publicized. The attacks on Friday were mainly due to a presumably coordinated attacker spinning up a bunch of machines on Scaleway cloud to use in a broad scanning campaign. Over the weekend, the exploit quickly lost popularity. This might be due to the fact that the exploit requires the Fabric Connector administrative interface to be publicly accessible, which is somewhat unlikely. While we cannot make predictions, CrowdSec expects exploitation signals to pick up slightly this week as vulnerability scanners start looking for vulnerable devices. However, we don’t expect the attacker volume for this vulnerability to reach that of other Fortinet-related CVEs.

About the exploit:
The Fortinet FortiWeb Fabric Connector is an integration component designed to enhance application security by linking FortiWeb web application firewalls (WAFs) with other elements of the Fortinet Security Stack. It enables policy enforcement and automated threat response by leveraging intelligence gathered from FortiGate firewalls, FortiSandbox, FortiAnalyzer, and other “Fabric-enabled” devices. It is in some sense a glue product that holds an array of different Fortinet products together.
The vulnerability allows unauthenticated attackers to execute arbitrary SQL statements against the MySQL database connected to Fabric Connector. As this database runs as root per default, this attack can be chained to run arbitrary Python code on the affected machine, allowing attackers to further compromise the system. The vulnerability affects various FortiWeb versions from 7.0 to 7.6. As a workaround, the vendor recommends disabling the administrative interface to external visitors.
