CVE-2019-11542 is a post-authentication, administrator-level stack-based buffer overflow in DSHC Perl module implementations used by the Pulse Connect Secure and Pulse Policy Secure administrative web interface. Specially crafted administrative messages reach code that uses sprintf without appropriate bounds checking, permitting an authenticated administrator to overwrite stack memory. Affected Pulse Connect Secure versions are 9.0RX before 9.0R3.4, 8.3RX before 8.3R7.1, 8.2RX before 8.2R12.1, and 8.1RX before 8.1R15.1. Affected Pulse Policy Secure versions are 9.0RX before 9.0R3.2, 5.4RX before 5.4R7.1, 5.3RX before 5.3R12.1, 5.2RX before 5.2R12.1, and 5.1RX before 5.1R15.1.
