CVE-2022-45060 (GCVE-0-2022-45060)

Vulnerability from nvd – Published: 2022-11-09 00:00 – Updated: 2025-05-01 14:28
VLAI?
Summary
An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2, and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected.
Severity ?

CVE-2019-20637 (GCVE-0-2019-20637)

Vulnerability from nvd – Published: 2020-04-08 23:01 – Updated: 2024-08-05 02:46
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2019-15892 (GCVE-0-2019-15892)

Vulnerability from nvd – Published: 2019-09-03 20:56 – Updated: 2024-08-05 01:03
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2017-12425 (GCVE-0-2017-12425)

Vulnerability from nvd – Published: 2017-08-04 09:00 – Updated: 2024-08-05 18:36
VLAI?
Summary
An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases.
Severity ?
No CVSS data available.

CVE-2022-45060 (GCVE-0-2022-45060)

Vulnerability from cvelistv5 – Published: 2022-11-09 00:00 – Updated: 2025-05-01 14:28
VLAI?
Summary
An HTTP Request Forgery issue was discovered in Varnish Cache 5.x and 6.x before 6.0.11, 7.x before 7.1.2, and 7.2.x before 7.2.1. An attacker may introduce characters through HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This could, in turn, be used to exploit vulnerabilities in a server behind the Varnish server. Note: the 6.0.x LTS series (before 6.0.11) is affected.
Severity ?

CVE-2019-20637 (GCVE-0-2019-20637)

Vulnerability from cvelistv5 – Published: 2020-04-08 23:01 – Updated: 2024-08-05 02:46
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2019-15892 (GCVE-0-2019-15892)

Vulnerability from cvelistv5 – Published: 2019-09-03 20:56 – Updated: 2024-08-05 01:03
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2017-12425 (GCVE-0-2017-12425)

Vulnerability from cvelistv5 – Published: 2017-08-04 09:00 – Updated: 2024-08-05 18:36
VLAI?
Summary
An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases.
Severity ?
No CVSS data available.

A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases."
