CVSS: 8.8EPSS: 0%CPEs: 2EXPL: 0CVE-2022-43608 – Canon imageCLASS MF644Cdw BJNP Integer Overflow Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2022-43608
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Canon imageCLASS MF644Cdw 10.03 printers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the BJNP service. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of root. • https://www.psirt.canon/advisory-information/cve-2022-43608_20221125 https://www.zerodayinitiative.com/advisories/ZDI-22-1666 • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2022-24673
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Canon imageCLASS MF644Cdw 10.02 printers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the SLP protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. • https://www.usa.canon.com/support/canon-product-advisories/canon-laser-printer-inkjet-printer-and-small-office-multifunctional-printer-measure-against-buffer-overflow https://www.zerodayinitiative.com/advisories/ZDI-22-515 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
