CISA Warns of Active exploitation of JasperReports Vulnerabilities

The U.S. Cybersecurity and Infrastructure Security Agency (CISA)
has added^[1]
two-years-old security flaws impacting TIBCO Software’s
JasperReports product to its Known Exploited Vulnerabilities
(KEV^[2]) catalog, citing
evidence of active exploitation.

The flaws, tracked as CVE-2018-5430^[3]
(CVSS score: 7.7) and CVE-2018-18809^[4]
(CVSS score: 9.9), were addressed by TIBCO in April 2018 and March
2019, respectively.

TIBCO JasperReports^[5]
is a Java-based reporting and data analytics platform for creating,
distributing, and managing reports and dashboards.

The first of the two issues, CVE-2018-5430, relates to an
information disclosure bug^[6] in the server component
that could enable an authenticated user to gain read-only access to
arbitrary files, including key configurations.

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

CVE-2018-18809, on the other hand, is a directory traversal vulnerability^[7] in the JasperReports
Library that could permit web server users to access sensitive
files on the host, potentially making it possible for an attacker
to steal credentials and break into other systems.

CISA did not disclose any additional specifics about how the
vulnerabilities are being weaponized in real-world attacks. Federal
agencies in the U.S. are required to patch their systems by January
19, 2023.
