CVE-2023-29552 is a high-severity vulnerability (7.5) affecting the Service Location Protocol (SLP), which allows an unauthenticated, remote attacker to register arbitrary services and potentially launch a denial-of-service attack with a significant amplification factor. This vulnerability impacts various systems, including those running NetApp SMI-S Provider, SUSE Manager Server, SUSE Linux Enterprise Server, and VMware ESXi. It's important for users to be aware of this issue and take necessary precautions to protect their systems.
How do I know if I'm affected?
To determine if you're affected by this vulnerability, you should check if you're using any of the following systems: NetApp SMI-S Provider, SUSE Manager Server, SUSE Linux Enterprise Server versions 11, 12, and 15 (including SAP versions), VMware ESXi versions up to (excluding) 7.0, and Service Location Protocol Project's Service Location Protocol. If you're using any of these systems, you may be at risk and should take necessary precautions to protect your systems.
What should I do if I'm affected?
If you're affected by the CVE-2023-29552 vulnerability, take these steps to protect your system: 1) Disable SLP if it's not needed, 2) Add a blocking firewall ruleset for TCP/UDP at port 427, and 3) Configure SLP to disable registration of extra services without authentication or signed messages. If these steps don't work, contact your vendor for further assistance.
Is this in CISA’s Known Exploited Vulnerabilities Catalog?
The CVE-2023-29552 vulnerability is indeed listed in CISA's Known Exploited Vulnerabilities Catalog. This high-severity issue, known as the Service Location Protocol (SLP) Denial-of-Service Vulnerability, was added to the catalog on November 8, 2023, with a due date of November 29, 2023. To address this vulnerability, organizations are required to apply mitigations as per vendor instructions or disable the SLP service or port 427/UDP on all systems running on untrusted networks, including those directly connected to the internet.
Weakness enumeration
The weakness enumeration for this vulnerability is "Insufficient Information", indicating a lack of specific details about the vulnerability and its mitigation. involves a Denial-of-Service (DoS) Amplification Attack in the Service Location Protocol (SLP). Defense mechanisms include disabling SLP, blocking port 427, and disabling registration of extra services without authentication.
