A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether.

The remote Rocky Linux 9 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2024:1750 advisory.

  - A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside     the unbound group to modify the unbound runtime configuration.

This flaw allows an unprivileged attacker to     manipulate a running instance, potentially altering forwarders, allowing them to track all queries     forwarded by the local resolver, and, in some cases, disrupting resolving altogether. (CVE-2024-1488)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the unbound packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote     attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the     'KeyTrap' issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the     protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG     records. (CVE-2023-50387)

  - The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped)     allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC     responses in a random subdomain attack, aka the 'NSEC3' issue. The RFC 5155 specification implies that an     algorithm must perform thousands of iterations of a hash function in certain situations. (CVE-2023-50868)

  - A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside     the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to     port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to     manipulate a running instance, potentially altering forwarders, allowing them to track all queries     forwarded by the local resolver, and, in some cases, disrupting resolving altogether. (CVE-2024-1488)
