The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5474-1 advisory.

    It was dicovered that Varnish Cache did not clear a pointer between the handling of one client request and     the next request within the same connection. A remote attacker could possibly use this issue to obtain     sensitive information. (CVE-2019-20637)

    It was discovered that Varnish Cache could have an assertion failure when a TLS termination proxy uses     PROXY version 2. A remote attacker could possibly use this issue to restart the daemon and cause a     performance loss. (CVE-2020-11653)

    It was discovered that Varnish Cache allowed request smuggling and VCL authorization bypass via a large     Content-Length header for a POST request. A remote attacker could possibly use this issue to obtain     sensitive information. (CVE-2021-36740)

    It was discovered that Varnish Cache allowed request smuggling for HTTP/1 connections. A remote attacker     could possibly use this issue to obtain sensitive information. (CVE-2022-23959)

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2022:0024 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-15892:
    An issue was discovered in Varnish Cache before 6.0.4 LTS, and 6.1.x and 6.2.x before 6.2.1. An HTTP/1     parsing failure allows a remote attacker to trigger an assert by sending crafted HTTP/1 requests. The     assert will cause an automatic restart with a clean cache, which makes it a Denial of Service attack.

    CVE-2019-20637:
    An issue was discovered in Varnish Cache before 6.0.5 LTS, 6.1.x and 6.2.x before 6.2.2, and 6.3.x before     6.3.1. It does not clear a pointer between the handling of one client request and the next request within     the same connection. This sometimes causes information to be disclosed from the connection workspace, such     as data structures associated with previous requests within this connection or VCL-related temporary     headers.

    CVE-2022-23959:
    In Varnish Cache before 6.6.2 and 7.x before 7.0.2, Varnish Cache 6.0 LTS before 6.0.10, and and Varnish     Enterprise (Cache Plus) 4.1.x before 4.1.11r6 and 6.0.x before 6.0.9r4, request smuggling can occur for     HTTP/1 connections.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0148-1 advisory.

  - Varnish Cache, with HTTP/2 enabled, allows request smuggling and VCL authorization bypass via a large     Content-Length header for a POST request. This affects Varnish Enterprise 6.0.x before 6.0.8r3, and     Varnish Cache 5.x and 6.x before 6.5.2, 6.6.x before 6.6.1, and 6.0 LTS before 6.0.8. (CVE-2021-36740)

The version of varnish installed on the remote host is prior to 4.0.5-3.23. It is, therefore, affected by a vulnerability as referenced in the ALAS-2022-1632 advisory.

    A flaw was found in Varnish. This flaw allows an attacker to carry out a request smuggling attack on     HTTP/1 connections on Varnish cache servers. This smuggled request goes through the usual Varnish     Configuration Language (VCL) processing since the Varnish server treats it as an additional request.
    (CVE-2022-23959)

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2920 advisory.

    James Kettle discovered that a request smuggling attack can be performed on HTTP/1 connections on Varnish     servers, high-performance web accelerators. The smuggled request would be treated as an additional request     by the Varnish server which may lead to information disclosure and cache poisoning. For Debian 9 stretch,     this problem has been fixed in version 5.0.0-7+deb9u3. We recommend that you upgrade your varnish     packages.
