Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) HTTP request smuggling attack (CVE-ID: CVE-2017-7656)
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.
2) Information disclosure (CVE-ID: CVE-2017-7657)
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.
3) HTTP request smuggling attack (CVE-ID: CVE-2017-7658)
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 HTTP requests that contain more than one content-length header. A remote attacker can send a specially crafted HTTP request that contains a transfer-encoding header and a content-length header, cause the software and an upstream HTTP agent to misinterpret the boundary of the request and to poison the web cache on the system, which could be used to conduct further attacks.
4) Session fixation attack (CVE-ID: CVE-2018-12538)
The vulnerability allows a remote attacker to a session fixation attack on a target system.
The vulnerability exists due to improper security restrictions when the FileSessionDataStore class is used for persistent storage of HTTP session details. A remote attacker can submit a partial session ID, delete other unmatched HTTP sessions from filesystem storage for the FileSessionDataStore class and hijack existing HTTP sessions or cause the service to crash.
5) Information disclosure (CVE-ID: CVE-2018-12536)
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.
