Description
This security bulletin contains information about 1 vulnerability.
1) Information disclosure (CVE-ID: CVE-2018-1323)
CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to incorrect handling of some edge cases by the IIS/ISAPI specific code that normalised the requested path before matching it to the URI-worker map. A remote attacker can send a specially constructed request to expose application functionality through the reverse proxy that was not intended for clients accessing the application via the reverse proxy.
Remediation
