CVE-2024-47176: AUTOMATED SCANNER HELPS SECURE LINUX SYSTEMS AGAINST RCE ATTACKS
- #CVE-2024-47176

A critical vulnerability in the Common UNIX Printing System (CUPS), specifically
identified as CVE-2024-47176 along with three other related vulnerabilities,
poses a significant risk for Distributed Denial-of-Service (DDoS) and remote
code execution (RCE) attacks. Affecting over 198,000 internet-exposed devices,
this flaw allows attackers to exploit the CUPS server to generate large IPP/HTTP
requests, consuming bandwidth and CPU resources of both the server and target.
Akamai's research highlights that many of these devices run outdated versions of
CUPS, dating back to 2007, making them particularly susceptible to exploitation.
Security researchers have developed tools like `cups_scanner.py` to help detect
vulnerable instances and advise organizations to update or disable CUPS, or at
least firewall the service ports. Despite the availability of partial fixes,
real-world exploitation hasn't been observed yet, but the potential for
significant disruption remains high until a comprehensive mitigation strategy is
implemented.

SCAN AND PATCH CUPS VULNERABILITIES IN LINUX TO PREVENT REMOTE ATTACKS

WritePreview
Researchers have identified four critical vulnerabilities in the Common UNIX
Printing System (CUPS), known as CVE-2024-47176, CVE-2024-47076, CVE-2024-47175,
and CVE-2024-47177, which could be exploited for remote code execution (RCE) and
distributed denial-of-service (DDoS) attacks.

These vulnerabilities can be exploited by sending specially crafted packets that
trick the CUPS server into generating large IPP/HTTP requests towards a target,
consuming significant bandwidth and CPU resources.
