Description

This security bulletin contains information about 3 vulnerabilities.


1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2015-5739)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to conduct an HTTP request smuggling attack on the target system.

The vulnerability exists due to the "net/http" library in "net/textproto/reader.go" does not properly parse HTTP header keys. A remote attacker can send a specially crafted HTTP request and conduct HTTP request smuggling attacks via a space instead of a hyphen, as demonstrated by "Content Length" instead of "Content-Length."



2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2015-5740)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to conduct an HTTP request smuggling attack on the target system.

The vulnerability exists due to the "net/http" library in "net/http/transfer.go" does not properly parse HTTP headers. A remote attacker can send a specially crafted HTTP request and conduct HTTP request smuggling attacks via a request with two Content-length headers.

3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2015-5741)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The net/http library in net/http/transfer.go in Go before 1.4.3 does not properly parse HTTP headers, which allows remote attackers to conduct HTTP request smuggling attacks via a request that contains Content-Length and Transfer-Encoding header fields.
