CVE-2022-23437: Infinite loop within Apache XercesJ xml parser

MediumCVSS 6.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 29/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 11.6% (FIRST EPSS); higher than 96% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: libxerces2-java (Debian:12) 2.12.2-1; xerces:xercesImpl (Maven) 2.12.2; xerces-j2 (openSUSE:Leap 15.3) 2.12.0-3.3.1, 2.11.0-4.3.1.

Low priority for now. Upgrade to libxerces2-java (Debian:12) 2.12.2-1; xerces:xercesImpl (Maven) 2.12.2; xerces-j2 (openSUSE:Leap 15.3) 2.12.0-3.3.1, 2.11.0-4.3.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ version 2.12.1 and the previous versions.
