Missing Encryption of Sensitive Data

In Waitress through version 1.4.0, if a proxy server is used in front of waitress, an invalid request may be sent by an attacker

CVE-2019-16789 8.2 - High - December 26, 2019

In Waitress through version 1.4.0, if a proxy server is used in front of waitress, an invalid request may be sent by an attacker that bypasses the front-end and is parsed differently by waitress leading to a potential for HTTP request smuggling. Specially crafted requests containing special whitespace characters in the Transfer-Encoding header would get parsed by Waitress as being a chunked request, but a front-end server would use the Content-Length instead as the Transfer-Encoding header is considered invalid due to containing invalid characters. If a front-end server does HTTP pipelining to a backend Waitress server this could lead to HTTP request splitting which may lead to potential cache poisoning or unexpected information disclosure. This issue is fixed in Waitress 1.4.1 through more strict HTTP field validation.

HTTP Request Smuggling

Waitress through version 1.3.1 would parse the Transfer-Encoding header and only look for a single string value, if

CVE-2019-16786 7.5 - High - December 20, 2019

Waitress through version 1.3.1 would parse the Transfer-Encoding header and only look for a single string value, if that value was not chunked it would fall through and use the Content-Length header instead. According to the HTTP standard Transfer-Encoding should be a comma separated list, with the inner-most encoding first, followed by any further transfer codings, ending with chunked. Requests sent with: "Transfer-Encoding: gzip, chunked" would incorrectly get ignored, and the request would use a Content-Length header instead to determine the body size of the HTTP message. This could allow for Waitress to treat a single request as multiple requests in the case of HTTP pipelining. This issue is fixed in Waitress 1.4.0.

HTTP Request Smuggling

Waitress through version 1.3.1 implemented a "MAY" part of the RFC7230

CVE-2019-16785 7.5 - High - December 20, 2019

Waitress through version 1.3.1 implemented a "MAY" part of the RFC7230 which states: "Although the line terminator for the start-line and header fields is the sequence CRLF, a recipient MAY recognize a single LF as a line terminator and ignore any preceding CR." Unfortunately if a front-end server does not parse header fields with an LF the same way as it does those with a CRLF it can lead to the front-end and the back-end server parsing the same HTTP message in two different ways. This can lead to a potential for HTTP request smuggling/splitting whereby Waitress may see two requests while the front-end server only sees a single HTTP message. This issue is fixed in Waitress 1.4.0.

A vulnerability was found in openstack-ironic-inspector all versions excluding 5.0.2, 6.0.3, 7.2.4, 8.0.3 and 8.2.1

CVE-2019-10141 9.1 - Critical - July 30, 2019

A vulnerability was found in openstack-ironic-inspector all versions excluding 5.0.2, 6.0.3, 7.2.4, 8.0.3 and 8.2.1. A SQL-injection vulnerability was found in openstack-ironic-inspector's node_cache.find_node(). This function makes a SQL query using unfiltered data from a server reporting inspection results (by a POST to the /v1/continue endpoint). Because the API is unauthenticated, the flaw could be exploited by an attacker with access to the network on which ironic-inspector is listening. Because of how ironic-inspector uses the query results, it is unlikely that data could be obtained. However, the attacker could pass malicious data and create a denial of service.

An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c

CVE-2018-17204 4.3 - Medium - September 19, 2018

An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default.

assertion failure

An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting ofproto_rule_insert__ in ofproto/ofproto.c

CVE-2018-17205 7.5 - High - September 19, 2018

An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting ofproto_rule_insert__ in ofproto/ofproto.c. During bundle commit, flows that are added in a bundle are applied to ofproto in order. If a flow cannot be added (e.g., the flow action is a go-to for a group id that does not exist), OvS tries to revert back all previous flows that were successfully applied from the same bundle. This is possible since OvS maintains list of old flows that were replaced by flows from the bundle. While reinserting old flows, OvS has an assertion failure due to a check on rule state != RULE_INITIALIZED. This would work for new flows, but for an old flow the rule state is RULE_REMOVED. The assertion failure causes an OvS crash.
