cups-browsed

CUPS cups-browsed before 2.5b1 will send an HTTP POST request to an arbitrary destination and port in response to a single IPP UDP packet requesting a printer to be added, a different vulnerability than CVE-2024-47176. (The request is meant to probe the new printer but can be used to create DDoS amplification attacks.)

CVE-2024-47850 is a vulnerability affecting cups-browsed, a component of the Common UNIX Printing System (CUPS) responsible for discovering and managing network printers. In versions prior to 2.5b1, cups-browsed responds to a single IPP (Internet Printing Protocol) UDP packet requesting a printer to be added by sending an HTTP POST request to an arbitrary destination and port specified by the attacker. This behavior is distinct from CVE-2024-47176 and can be leveraged to perform Distributed Denial of Service (DDoS) amplification attacks. The vulnerability arises because the service acts as an open reflector, allowing attackers to amplify traffic towards victim systems by spoofing IPP UDP packets. The CVSS 3.1 score of 7.5 reflects high severity, with an attack vector over the network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), but high impact on availability (A:H). The weakness is classified under CWE-400 (Uncontrolled Resource Consumption), indicating that the vulnerability can cause resource exhaustion or service disruption. No patches or exploits are currently publicly available, but the risk remains significant due to the ease of exploitation and potential for large-scale DDoS attacks leveraging multiple vulnerable hosts.

CVE-2024-47850: n/a

CUPS is a standards-based, open-source printing system, and `cups-browsed` contains network printing functionality including, but not limited to, auto-discovering print services and shared printers. `cups-browsed` binds to `INADDR_ANY:631`, causing it to trust any packet from any source, and can cause the `Get-Printer-Attributes` IPP request to an attacker controlled URL. When combined with other vulnerabilities, such as CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177, an attacker can execute arbitrary commands remotely on the target machine without authentication when a malicious printer is printed to.

CVE-2024-47176 affects the cups-browsed component of the OpenPrinting system, which is responsible for network printing functionalities including auto-discovery of print services and shared printers. The vulnerability arises because cups-browsed binds its listening socket to INADDR_ANY on port 631, meaning it listens on all network interfaces without restriction. This design flaw allows the service to accept IPP (Internet Printing Protocol) requests from any source IP address, including potentially malicious external hosts. Specifically, an attacker can send a crafted Get-Printer-Attributes IPP request to a URL controlled by the attacker. While this alone does not directly lead to code execution, it sets the stage for exploitation when combined with other vulnerabilities in the same component (CVE-2024-47076, CVE-2024-47175, CVE-2024-47177). Together, these vulnerabilities enable an attacker to execute arbitrary commands remotely on the target system without requiring authentication or user interaction. The affected versions are cups-browsed versions up to 2.0.1. The CVSS v3.1 score is 5.3 (medium), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and limited impact on integrity but no impact on confidentiality or availability. No patches or exploits are currently publicly available, but the vulnerability is published and should be addressed promptly. The root cause is categorized under CWE-1327, which involves binding to an unrestricted IP address, leading to exposure of services to untrusted networks.
