CVE-2019-9901

Envoy 1.9.0 and before does not normalize HTTP URL paths. A remote attacker may craft a relative path, e.g., something/../admin, to bypass access control, e.g., a block on /admin. A backend server could then interpret the non-normalized path and provide an attacker access beyond the scope provide...

CVE-2019-9901

CVE-2019-9901 affects Envoy 1.9.0 and earlier. The vulnerability arises because Envoy does not normalize HTTP URL paths, allowing a remote attacker to craft a relative path (e.g., something/../admin) to bypass access controls and cause a backend to interpret a non-normalized path, potentially gra...

CVE-2019-9900

When parsing HTTP/1.x header values, Envoy 1.9.0 and before does not reject embedded zero characters NUL, ASCII 0x0. This allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules, gaining access to unauthorized resources...

FreeBSD : Istio -- Security vulnerabilities (484d3f5e-653a-11e9-b0e3-1c39475b9f84)

Istio reports : Two security vulnerabilities have recently been identified in the Envoy proxy. The vulnerabilities are centered on the fact that Envoy did not normalize HTTP URI paths and did not fully validate HTTP/1.1 header values. These vulnerabilities impact Istio features that rely on Envoy...

PT-2019-2303

Name of the Vulnerable Software and Affected Versions Envoy versions 1.9.0 and earlier Description The issue is related to errors in parsing HTTP headers and URL paths.

Node.js: Vulnerability in http-parser & embedded NULL header handling

Due to a snafu in how [email protected] is setup to forward see https://github.com/envoyproxy/envoy/issues/5155, the following bug report was not made available prior to disclosure. For completeness, I'm providing the original e-mail below. Please note that this has been fixed in http-parser...

istio/envoy: Authorization bypass via null characters injection in HTTP/1.x

A flaw was found in Envoy version 1.9.0 and older, where Envoy does not reject embedded zero characters NUL, ASCII 0x0 when processing HTTP/1.x header values. This flaw allows remote attackers crafting header values containing embedded NUL characters to potentially bypass header matching rules,...

istio/envoy: Path traversal via URL Patch manipulation in HTTP/1.x header

A flaw was found in Envoy version 1.9.0 and older, where Envoy does not normalize HTTP URL paths. This flaw allows a remote attacker to craft a path with a relative path and to bypass access control. This issue results in a backend server with the ability to interpret the unnormalized path...
