Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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: 22.9% (FIRST EPSS); higher than 97.7% of all records.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Cross-site scripting (XSS) in Internet Explorer 5.5 and 6.0, possibly in a component that is also used by other Microsoft products, allows remote attackers to insert arbitrary web script via an XML file that contains a parse error, which inserts the script in the resulting error message.
