The disclosed vulnerability allows a remote attacker to conduct an HTTP request smuggling attack on the target system.
The vulnerability exists due to improper handling of HTTP/0.9 requests. A remote attacker can send a specially crafted HTTP/0.9 request that submits malicious request headers, cause the software and an upstream HTTP agent to misinterpret the boundary of the request and poison the web cache on the system, which could be used to conduct further attacks.
3) Information disclosure (CVE-ID: CVE-2017-7657)
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:U/U:Clear
The disclosed vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The vulnerability exists due to improper handling of queries that do not match the dynamic URL pattern for webapps that use default error handling settings. A remote attacker can send a query that submits malicious input, trigger a java.nio.file.InvalidPathException message, which could allow the attacker to view sensitive information, such as the software installation path.
