CVE-2021-3495 (GCVE-0-2021-3495)
Vulnerability from nvd – Published: 2021-06-01 13:31 – Updated: 2024-08-03 16:53
VLAI?
Summary
An incorrect access control flaw was found in the kiali-operator in versions before 1.33.0 and before 1.24.7. This flaw allows an attacker with a basic level of access to the cluster (to deploy a kiali operand) to use this vulnerability and deploy a given image to anywhere in the cluster, potentially gaining access to privileged service account tokens. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Severity ?

CVE-2020-8595 (GCVE-0-2020-8595)
Vulnerability from nvd – Published: 2020-02-12 14:10 – Updated: 2024-08-04 10:03
VLAI?
Summary
Istio versions 1.2.10 (End of Life) and prior, 1.3 through 1.3.7, and 1.4 through 1.4.3 allows authentication bypass. The Authentication Policy exact-path matching logic can allow unauthorized access to HTTP paths even if they are configured to be only accessed after presenting a valid JWT token. For example, an attacker can add a ? or # character to a URI that would otherwise satisfy an exact-path match.
Severity ?
No CVSS data available.

CVE-2019-9518 (GCVE-0-2019-9518)
Vulnerability from nvd – Published: 2019-08-13 20:50 – Updated: 2024-08-04 21:54

Title
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service
Summary
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
Severity ?
7.5 (High)

CVE-2019-9517 (GCVE-0-2019-9517)
Vulnerability from nvd – Published: 2019-08-13 20:50 – Updated: 2024-08-04 21:54
VLAI?
Title
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service
Summary
Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both.
Severity ?
7.5 (High)
CWE
- CWE-400 - Uncontrolled Resource Consumption

"value": "Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both."

The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both."

Title
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service
Summary
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
Severity ?
7.5 (High)
CWE
- CWE-400 - Uncontrolled Resource Consumption

CVE-2019-9515 (GCVE-0-2019-9515)
Vulnerability from nvd – Published: 2019-08-13 20:50 – Updated: 2024-08-04 21:54
VLAI?
Title
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service
Summary
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
Severity ?
7.5 (High)
CWE
- CWE-400 - Uncontrolled Resource Consumption

CVE-2021-3495 (GCVE-0-2021-3495)
Vulnerability from cvelistv5 – Published: 2021-06-01 13:31 – Updated: 2024-08-03 16:53
VLAI?
Summary
An incorrect access control flaw was found in the kiali-operator in versions before 1.33.0 and before 1.24.7. This flaw allows an attacker with a basic level of access to the cluster (to deploy a kiali operand) to use this vulnerability and deploy a given image to anywhere in the cluster, potentially gaining access to privileged service account tokens. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Severity ?
No CVSS data available.

CVE-2020-8595 (GCVE-0-2020-8595)
Vulnerability from cvelistv5 – Published: 2020-02-12 14:10 – Updated: 2024-08-04 10:03
VLAI?
Summary
Istio versions 1.2.10 (End of Life) and prior, 1.3 through 1.3.7, and 1.4 through 1.4.3 allows authentication bypass. The Authentication Policy exact-path matching logic can allow unauthorized access to HTTP paths even if they are configured to be only accessed after presenting a valid JWT token. For example, an attacker can add a ? or # character to a URI that would otherwise satisfy an exact-path match.
Severity ?
No CVSS data available.
