Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), OffSeq Mirage (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Upgrade cups-browsed to a version later than 2.0.1 once patches become available from the OpenPrinting project or your Linux distribution vendor. 2. Until patches are applied, restrict network access to port 631 on systems running cups-browsed by implementing firewall rules that limit connections to trusted internal IP addresses only. 3. Disable cups-browsed or the network printing service on systems where it is not required, especially on publicly accessible or untrusted network interfaces. 4. Monitor network traffic for unusual IPP requests or connections to port 631 from unexpected sources. 5. Employ network segmentation to isolate print servers from critical infrastructure and sensitive data environments. 6. Review and apply security best practices for print server hardening, including disabling unnecessary features and enabling logging and alerting for suspicious activities. 7. Stay informed about updates regarding the related vulnerabilities (CVE-2024-47076, CVE-2024-47175, CVE-2024-47177) and apply combined patches promptly to prevent chained exploitation.

Description

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.

Impact

For European organizations, this vulnerability poses a moderate risk primarily in environments where cups-browsed is deployed on networked printing infrastructure accessible from untrusted networks or segments. The ability for an unauthenticated attacker to send malicious IPP requests could lead to unauthorized command execution when combined with other vulnerabilities, potentially compromising print servers and connected systems. This could result in disruption of printing services, unauthorized access to sensitive documents, lateral movement within internal networks, and potential data integrity issues. Organizations with large-scale print deployments, especially in sectors like government, finance, healthcare, and manufacturing, may face increased risk due to the critical nature of printing infrastructure. The vulnerability could also be leveraged as an initial foothold for further attacks if exploited in combination with the related CVEs. However, the absence of known exploits in the wild and the medium severity rating suggest that immediate widespread impact is limited but should not be underestimated.
