CVE-2024-47076 METASPLOIT HIGH ruby WORKING POC
libcupsfilters < 2.0.0 - Improper Input Validation in cfGetPrinterAttributes5
CUPS is a standards-based, open-source printing system, and `libcupsfilters` contains the code of the filters of the former `cups-filters` package as library functions to be used for the data format conversion tasks needed in Printer Applications. The `cfGetPrinterAttributes5` function in `libcupsfilters` does not sanitize IPP attributes returned from an IPP server. When these IPP attributes are used, for instance, to generate a PPD file, this can lead to attacker controlled data to be provided to the rest of the CUPS system.

Rejected
Rejected reason: ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2024-47076, CVE-2024-47175, CVE-2024-47176. Reason: This candidate is a duplicate of CVE-2024-47076, CVE-2024-47175, and CVE-2024-47176. Notes: All CVE users should reference CVE-2024-47076, CVE-2024-47175, and/or CVE-2024-47176 instead of this candidate. This CVE was issued to a vulnerability that is dependent on CVE-2024-47076, CVE-2024-47175, and CVE-2024-47176. According to rule 4.2.15 of the CVE CNA rules, \"CNAs MUST NOT assign a different CVE ID to a Vulnerability that is fully interdependent with another Vulnerability. The Vulnerabilities are effectively the same single Vulnerability and MUST use one CVE ID.
CVE-2024-47175 METASPLOIT HIGH ruby WORKING POC
OpenPrinting libppd - Unsanitized IPP Attribute Code Execution
CUPS is a standards-based, open-source printing system, and `libppd` can be used for legacy PPD file support. The `libppd` function `ppdCreatePPDFromIPP2` does not sanitize IPP attributes when creating the PPD buffer. When used in combination with other functions such as `cfGetPrinterAttributes5`, can result in user controlled input and ultimately code execution via Foomatic. This vulnerability can be part of an exploit chain leading to remote code execution (RCE), as described in CVE-2024-47176.

CVE-2024-47176 METASPLOIT MEDIUM ruby WORKING POC
OpenPrinting cups-browsed - Attacker-Controlled IPP Request Server-Side Request Forgery
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.
