1) Information disclosure
EUVDB-ID: #VU13126
Risk: Low
CVSSv4.0: 2.7 [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]
CVE-ID: CVE-2018-11469
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists in the check_request_for_cacheability function of HAProxy due to improper caching of responses for requests that include an authorization header by the check_request_for_cacheability function, as defined in the proto_http.csource code file. A remote attacker can send a specially crafted request and access sensitive information, which could be used to conduct further attacks.
