Critical Linux CUPS Printing System Flaws Could Lead to Remote Command Execution

CUPS (Common UNIX Printing System) is a standards-based, open-source printing system. Recent several vulnerabilities (CVE-2024-47076, CVE-2024-47175, CVE-2024-47176, CVE-2024-47177) were discovered and are potentially allowing hackers to remotely run code on machines that expose the service over UDP (usually, on port 631).

It is recommended to block ports for UDP. It is a good practice to avoid open IPP services also over UDP.

As checking for affected UDP open services triggers a connection from the vulnerable machine to the attacking system, and relying on the fact that most of the detected vulnerable systems over UDP had open IPP service over TCP on the same port, IONIX marks assets as potentially affected based on services with open IPP ports (TCP). Notice, that having IPP service publicly open is also not a good practice, and we recommend to close it as well.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
