Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) HTTP request smuggling attack
EUVDB-ID: #VU13527
Risk: Low
CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7656
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe 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.
MitigationUpdate the affected package to version: 9.2.21-1+deb9u1
Vulnerable software versionsDebian Linux: All versions

2) Information disclosure
EUVDB-ID: #VU13528
Risk: Low
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7657
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe 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.

CVE-ID: CVE-2017-7658
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe 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.
