The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue.

Certain HP Print products and Digital Sending products may be vulnerable to potential remote code execution and buffer overflow with use of Link-Local Multicast Name Resolution or LLMNR.

During installation with certain driver software or application packages an arbitrary code execution could occur.

The PML Driver HPZ12 (HPZipm12.exe) in the HP all-in-one drivers, as used by multiple HP products, uses insecure SERVICE_CHANGE_CONFIG DACL permissions, which allows local users to gain privileges and execute arbitrary programs, as demonstrated by modifying the binpath argument, a related issue to CVE-2006-0023.
