Doc Text:
A flaw was found in OpenPrinting CUPS. In certain conditions, a remote attacker can add a malicious printer or directly hijack an existing printer by replacing the valid IPP URL with a malicious one. Also, it is possible that due to a lack of validation of IPP attributes returned by the server, this issue allows attacker-controlled data to be used on the rest of the CUPS system.

Description OSIDB Bzimport 2024-09-23 16:57:13 UTC 
If an attacker is able to exploit an exposed IPP server to respond with a valid response to be added to the system, and if discovered via mDNS, an existing printer can be directly hijacked (its IPP url replaced with a malicious one) making it indistinguishable from the original one. The `cfGetPrinterAttributes` API does not perform any sanitization on any of the IPP attributes returned by the server. Attributes that are then saved, as they are, in a temporary PPD file via `ppdCreatePPDFromIPP2`. `ppdCreatePPDFromIPP2` doesn't perform any sanitization itself and in fact it just writes to the file any attributes contents. This allows an attacker to return a malicious IPP attribute in the form of `printer-privacy-policy-uri` (which is just one of the several attributes that can be used, the RCE was also confirmed with `printer-info`, `printer-name` and `printer-make-and-model`).
