Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability allows an attacker to execute arbitrary operating system commands as root on the machine running the Flowints application. This is possible by creating a sketch and then triggering a specific transformation, which can lead to a Docker container escape.
- Can affect sensitive data and systems.
- Requires an attacker to interact with the application.
Attack Path
How an attacker could exploit the issue
An attacker could weaponize this by creating a sketch and then triggering the `org_to_asn` transform on an organization node. This would execute arbitrary OS commands as root on the host machine by exploiting shell metacharacters and a Docker container escape.
- No authentication required.
- Target: `org_to_asn` transform.
- Requires sketch creation.
Live Threat
Current exploitation, exposure, and threat context
Attackers will likely be interested in weaponizing this critical vulnerability due to its potential for remote command execution as root. The ease of triggering the vulnerability by creating a sketch and performing a specific transform, combined with its network accessibility, makes it an attractive target for broad exploitation. While not yet officially listed on known exploited vulnerability catalogs, its inherent characteristics suggest a significant threat potential.
- Public exploit availability is unknown.
- No KEV listing observed.
- Fix released recently.
Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
Prioritize isolating or taking offline affected Flowsint services due to the critical severity and known vulnerability allowing remote command execution as root. Investigate logs for signs of the 'org_to_asn' transform being triggered and identify all instances of Flowsint that could be susceptible to this escape.
- Block network access to vulnerable instances.
- Apply patch commit b52cbbb904c8013b74308d58af88bc7dbb1b055c.
- Monitor for suspicious root-level commands.
