Vulnerabilities

CKAN MCP Server is a tool for querying CKAN open data portals. Versions prior to 0.4.85 provide tools including ckan_package_search and sparql_query that accept a base_url parameter, making HTTP requests to arbitrary endpoints without restriction. A CKAN portal client has no legitimate reason to contact cloud metadata or internal network services. There is no URL validation on base_url parameter. No private IP blocking (RFC 1918, link-local 169.254.x.x), no cloud metadata blocking. The sparql_query and ckan_datastore_search_sql tools also accept arbitrary base URLs and expose injection surfaces. An attack can lead to internal network scanning, cloud metadata theft (IAM credentials via IMDS at 169.254.169.254), potential SQL/SPARQL injection via unsanitized query parameters. Attack requires prompt injection to control the base_url parameter. This issue has been fixed in version 0.4.85.

In Rollback Rx Professional 12.8.0.0, the driver file shieldm.sys allows local users to cause a denial of service because of a null pointer dereference from IOCtl 0x96202000.

CVE-2024-12084 is a critical (CVSS 9.8) heap-based buffer overflow in the rsync daemon, caused by improper handling of an attacker-controlled checksum length (s2length): when MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH of 16 bytes, a connecting peer can cause an out-of-bounds write into the fixed-size sum2 buffer. A remote attacker who can reach the rsync daemon needs no privileges or user interaction to trigger the flaw, and the resulting heap corruption can lead to remote code execution on the server (as demonstrated in the referenced Google security research) or crash the daemon. Any system running a vulnerable rsync daemon is affected — including rsync shipped with Red Hat Enterprise Linux, SUSE Linux, AlmaLinux, Arch Linux, Gentoo, NixOS and SmartOS — with the highest risk on servers where the daemon is exposed on TCP port 873. No confirmed in-the-wild exploitation is documented yet (the CVE is not on CISA KEV), but a public proof-of-concept exists from Google Cloud researchers and EPSS assigns a 72.1% probability of exploitation within 30 days, indicating high imminent risk.

Do: Upgrade rsync to 3.4.1 or later, or install the patched rsync package from your distribution (Red Hat, SUSE, AlmaLinux, Arch, Gentoo, NixOS and SmartOS have all shipped fixes). Until patched, restrict TCP port 873 to trusted networks or disable the rsync daemon where it is not needed. Audit hosts for listening rsync daemons and verify the installed rsync version against your vendor's advisory.

A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.

A flaw was found in New Horizon Datasys bootloaders before 2022-06-01. An attacker may use this bootloader to bypass or tamper with Secure Boot protections. In order to load and execute arbitrary code in the pre-boot stage, an attacker simply needs to replace the existing signed bootloader currently in use with this bootloader. Access to the EFI System Partition is required for booting using external media.
