Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2019-11510 is a path traversal vulnerability (CWE-22) affecting Pulse Secure Pulse Connect Secure (PCS) versions 8.2 before 8.2R12.1, 8.3 before 8.3R7.1, and 9.0 before 9.0R3.4. It allows an unauthenticated remote attacker to read arbitrary files on the affected appliance by submitting a specially crafted URI, and carries a CVSS 3.1 base score of 10.0 reflecting network attack vector, low complexity, and no required privileges or user interaction.

An attacker with network access can exploit the flaw to retrieve sensitive files such as configuration data or credentials stored on the VPN appliance. Successful file disclosure can expose session tokens, private keys, and other material that enables further compromise of the device and connected networks.

Public references document working proof-of-concept exploits, an Nmap NSE script for mass scanning, and reports of more than 14,500 exposed endpoints remaining vulnerable months after disclosure. Advisories and vendor guidance direct administrators to apply the fixed releases (8.2R12.1, 8.3R7.1, or 9.0R3.4) to eliminate the issue.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-10 Information Input Validation
addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

PR.PS-02 partial match
blocks

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
blocks

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.
