CVE-2005-1543· NVD / CVE Program· CNA mitre

Multiple stack-based and heap-based buffer overflows in Remote Management authentication (zenrem32.exe) on Novell ZENworks 6.5 Desktop and S

Noroxi assessment

Priority: Plan (action score 50/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 66.1% (FIRST EPSS); higher than 99.2% of all records.
  • No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple stack-based and heap-based buffer overflows in Remote Management authentication (zenrem32.exe) on Novell ZENworks 6.5 Desktop and Server Management, ZENworks for Desktops 4.x, ZENworks for Servers 3.x, and Remote Management allows remote attackers to execute arbitrary code via (1) unspecified vectors, (2) type 1 authentication requests, and (3) type 2 authentication requests.

  • Metasploit module ×1
  • Exploit-DB entry ×2

Noroxi does not host or link to exploit code. Metasploit module names and Nuclei template ids are shown (names, not code); Exploit-DB entries and PoC repositories are given as counts only.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
