            Guzzle/Nexmo Issues After Upgrading to Laravel 8
            Asked 2021-Jun-09 at 23:48

            I recently performed a rather large update to this web app, and for the most part it went off without a hitch... Until the app tries to send an SMS notification from staging/production.

            The upgrade from laravel 7.x to 8.x was quite simple and straightforward. At the same time we also installed Laravel Horizon. Everything went according to plan, and all works fine locally.

            When we deploy to staging/production however, queued SMS notifications fail with the following exception:

            ReflectionException: Class Http\Adapter\Guzzle6\Client does not exist in /home/forge/dev.example.com/releases/20210609194554/vendor/laravel/framework/src/Illuminate/Container/Container.php:836

            Looking in the stack trace we can see that Nexmo is the culprit:

            #5 /home/forge/dev.example.com/releases/20210609194554/vendor/nexmo/laravel/src/NexmoServiceProvider.php(150): Illuminate\Foundation\Application->make()

            However in our composer.json file we are requiring Guzzle 7 with the following:

            "guzzlehttp/guzzle": "^7.3",

            It is worth mentioning again at this point, I have no issues sending SMS locally, the main difference between local and staging environments is that locally I use Laravel Valet and Staging uses Laravel Envoyer.

            What I've tried so far:

            • Changing "guzzlehttp/guzzle": "^7.3" to "guzzlehttp/guzzle": "^6.5|^7.3"
            • Running php artisan horizon:purge and php artisan horizon:terminate both manually and in a deployment hook.
            • Restarting the laravel horizon daemon on forge.
            • trying php artisan queue:restart
            • running composer dump-autoload and composer dump-autoload -o
            • deleting composer.lock and the vendor/ directory from current/ then running composer install
            • Restarting PHP, Nginx, and eventually the entire server :(

            and more...

            Any help is greatly appreciated

            I see that the NexmoServiceProvider is trying to use the defined http_client in the config, so can you share what the .env has for NEXMO_HTTP_CLIENT ? I am pretty sure you have something wrong there or even not defined.

            And this is what it is defined in the config/nexmo.php related to that config:

            mTLS origination for egress traffic with custom mTLS between istio-proxy and egress gateway
            Asked 2021-Jun-09 at 08:40

            Our Security Dept requirement on egress traffic is very strict: Each app inside POD must go through some proxy with mTLS authentication (app-proxy) using dedicated cert for the app. They're suggesting using squid with tunneling to cope with double mTLS (one for proxy and the other one for the specific traffic app-server), but then we forced the app to be ssl-aware. Istio can come in and do the job but using out-of-the-box ISTIO_MUTUAL mode (between istio-proxy and egress gateway) is not the case for us.

            So, I've tried using example Configure mutual TLS origination for egress traffic by modifying it a bit as follows (changes marked with #- and #+):

            Yes, its a bit of a pain. There's an online envoy config checker that helps a bit in determining exactly which versions ditch backwards compatability.

            You have correctly switched from the legacy config to typed_config data.

            However, it looks like you inadvertently included a tab in your latest config (line 15) which causes illegal map value.

            k8s, Istio: remove transfer-encoding header

            In application's responses we see doubled transfer-encoding headers.
            Suppose, because of that we get 503 in UI, but at the same time application returns 201 in pod's logs.
            Except http code: 201 there are transfer-encoding=chunked and Transfer-Encoding=chunked headers in logs, so that could be a reason of 503.
            We've tried to remove transfer-encoding via Istio virtual service or envoy filter, but no luck..

            This is a community wiki answer. Feel free to expand it.

            As already discussed in the comments, the EnvoyFilter was not yet supported in Istio version 1.2 and actually that version is no longer in support since Dec 2019.

            I strongly recommend upgrading to the latest Istio and Envoy versions. Also, after you upgrade please notice that the filter name you want to use was deprecated and replaced. You should now use envoy.filters.network.tcp_proxy instead of envoy.tcp_proxy.

            Please remember that things are getting deprecated for a reason and keeping the old versions will sooner or later bring you more trouble. Try to keep things more up-to-date.

            More details can be found in the latest docs.

            Vulnerabilities

            Envoy before 1.16.1 logs an incorrect downstream address because it considers only the directly connected peer, not the information in the proxy protocol header. This affects situations with tcp-proxy as the network filter (not HTTP filters).
            Envoy before 1.16.1 mishandles dropped and truncated datagrams, as demonstrated by a segmentation fault for a UDP packet size larger than 1500.
            Envoy through 1.15.0 only considers the first value when multiple header values are present for some HTTP headers. Envoy’s setCopy() header map API does not replace all existing occurences of a non-inline header.
            Envoy master between 2d69e30 and 3b5acb2 may fail to parse request URL that requires host canonicalization.
            Istio through 1.5.1 and Envoy through 1.14.1 have a data-leak issue. If there is a TCP connection (negotiated with SNI over HTTPS) to *.example.com, a request for a domain concurrently configured explicitly (e.g., abc.example.com) is sent to the server(s) listening behind *.example.com. The outcome should instead be 421 Misdirected Request. Imagine a shared caching forward proxy re-using an HTTP/2 connection for a large subnet with many users. If a victim is interacting with abc.example.com, and a server (for abc.example.com) recycles the TCP connection to the forward proxy, the victim's browser may suddenly start sending sensitive data to a *.example.com server. This occurs because the forward proxy between the victim and the origin server reuses connections (which obeys the specification), but neither Istio nor Envoy corrects this by sending a 421 error. Similarly, this behavior voids the security model browsers have put in place between domains.
            In Envoy through 1.11.1, users may configure a route to match incoming path headers via the libstdc++ regular expression implementation. A remote attacker may send a request with a very long URI to result in a denial of service (memory consumption). This is a related issue to CVE-2019-14993.
            An issue was discovered in Envoy 1.12.0. An untrusted remote client may send HTTP/2 requests that write to the heap outside of the request buffers when the upstream is HTTP/1. This may be used to corrupt nearby heap contents (leading to a query-of-death scenario) or may be used to bypass Envoy's access control mechanisms such as path based routing. An attacker can also modify requests from other users that happen to be proximal temporally and spatially.
            An issue was discovered in Envoy 1.12.0. An untrusted remote client may send an HTTP header (such as Host) with whitespace after the header content. Envoy will treat "header-value " as a different string from "header-value" so for example with the Host header "example.com " one could bypass "example.com" matchers.
            A weak password vulnerability was discovered in Enphase Envoy R3.*.*. One can login via TCP port 8888 with the admin password for the admin account.
            CVE-2019-9901 CRITICAL
            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 provided for by the access control policy.
            In Envoy before versions 1.12.6, 1.13.4, 1.14.4, and 1.15.0 when validating TLS certificates, Envoy would incorrectly allow a wildcard DNS Subject Alternative Name apply to multiple subdomains. For example, with a SAN of *.example.com, Envoy would incorrectly allow nested.subdomain.example.com, when it should only allow subdomain.example.com. This defect applies to both validating a client TLS certificate in mTLS, and validating a server TLS certificate for upstream connections. This vulnerability is only applicable to situations where an untrusted entity can obtain a signed wildcard TLS certificate for a domain of which you only intend to trust a subdomain of. For example, if you intend to trust api.mysubdomain.example.com, and an untrusted actor can obtain a signed TLS certificate for *.example.com or *.com. Configurations are vulnerable if they use verify_subject_alt_name in any Envoy version, or if they use match_subject_alt_names in version 1.14 or later. This issue has been fixed in Envoy versions 1.12.6, 1.13.4, 1.14.4, 1.15.0.
            CNCF Envoy through 1.13.0 has incorrect Access Control when using SDS with Combined Validation Context. Using the same secret (e.g. trusted CA) across many resources together with the combined validation context could lead to the “static” part of the validation context to be not applied, even though it was visible in the active config dump.
            CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.
            Envoy version 1.14.2, 1.13.2, 1.12.4 or earlier may consume excessive amounts of memory when proxying HTTP/2 requests or responses with many small (i.e. 1 byte) data frames.
