CISA Adds JasperReports Flaws from 2018 to Known Exploited Vulnerabilities Catalog

Updated on 2022-12-30

The US Cybersecurity and Infrastructure Security Agency (CISA) has added two JasperReports vulnerabilities to its known exploited vulnerabilities catalog: CVE-2018-5430 (CVSS score: 7.7) and CVE-2018-18809 (CVSS score: 9.9). The flaws were disclosed in 2018; fixes are available for both flaws. CISA says it has become aware that the vulnerabilities – an information disclosure flaw in JasperReports Server and a directory traversal flaw in JasperReports Library – are being actively exploited. Federal civilian agencies have until January 19 to mitigate the flaws on their systems.


  • The two flaws, CVE-2018-5430 and CVE-2018-18809 have patches from TIBCO, also released in 2018. Make sure that you’re running the updated JasperReports server, library, and reporting engines.
  • The most obvious use of this database is to prioritize patching. However, consider consulting it as an indicator of quality before buying a product.
