Vulnerability mechanics

Root cause

"A buffer overflow vulnerability exists in the handling of print job data."

Attack vector

An attacker can send a specially crafted print job to the vulnerable LPD-LPR Print Server. This job contains an oversized buffer that overwrites critical control data on the stack. The exploit then redirects execution to shellcode embedded within the same payload, allowing arbitrary code execution with SYSTEM privileges [ref_id=1].

Affected code

The vulnerability lies within the NIPrint LPD-LPR Print Server, specifically in versions 4.10 and earlier. The exploit code targets a buffer overflow when processing print job data, leading to arbitrary code execution [ref_id=1].

What the fix does

The advisory does not provide specific details on a patch or remediation steps beyond recommending users upgrade to a non-vulnerable version. Therefore, the exact code changes that fix this vulnerability are not detailed.

Preconditions

  • inputThe target system must be running NIPrint LPD-LPR Print Server version 4.10 or earlier.
  • networkThe attacker must be able to send network traffic to the LPD-LPR Print Server on its listening port (typically 515).

Reproduction

The provided exploit code can be used to reproduce the vulnerability by targeting a vulnerable instance of the NIPrint LPD-LPR Print Server [ref_id=1].
