CISA Says Two Old JasperReports Vulnerabilities Exploited in Attacks

The US Cybersecurity and Infrastructure Security Agency (CISA) has added two JasperReports flaws to its Known Exploited Vulnerabilities Catalog.

The US Cybersecurity and Infrastructure Security Agency (CISA) has added two JasperReports flaws to its Known Exploited Vulnerabilities Catalog.

Tibco’s JasperReports Library is advertised as the world’s most popular open source reporting engine. The JasperReports Server software is designed to enable non-technical users to create reports, dashboards, and visualizations.

CISA has learned that two JasperReports vulnerabilities discovered in 2018 have been exploited in attacks.

One of them is CVE-2018-18809, a critical directory traversal issue in JasperReports Library that can allow webserver users to access data on the host system, which can include credentials for accessing other systems. The flaw was addressed in March 2019.

CVE-2018-18809 has been found to affect the products of major vendors that use the JasperReports Library, including IBM products.

The second vulnerability is CVE-2018-5430, a high-severity information disclosure issue affecting JasperReports Server. The security hole was addressed in April 2018.

“The impact includes the possible read-only access by authenticated users to web application configuration files that contain the credentials used by the server. Those credentials could then be used to affect external systems accessed by the JasperReports Server,” according to an advisory published at the time by Tibco.

Technical details and proof-of-concept (PoC) exploits are publicly available for both vulnerabilities.

There do not appear to be any public reports describing malicious exploitation of the two vulnerabilities, but CISA only adds flaws to its ‘Must Patch’ list if it has reliable evidence of exploitation in the wild.

SecurityWeek has reached out to Tibco for additional information and will update this article if the company responds.

Federal agencies have been instructed to patch CVE-2018-5430 and CVE-2018-18809 until January 19. Companies using the impacted products should also install the fixes as soon as possible.
