| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2022-1254 | A URL redirection vulnerability in Skyhigh SWG in main releases 10.x prior to 10.2.9, 9.x prior to 9.2.20, 8.x prior to 8.2.27, and 7.x prior to 7.8.2.31, and controlled release 11.x prior to 11.1.3 allows a remote attacker to redirect a user to a malicious website controlled by the attacker. This is possible because SWG incorrectly creates a HTTP redirect response when a user clicks a carefully constructed URL. Following the redirect response, the new request is still filtered by the SWG policy | [email protected] | 6.1 | 0.19% | 2022-04-20 | 2024-11-21 |
| CVE-2021-3450 | The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten.

| CVE-2021-3449 | An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). O | [email protected] | 5.9 | 9.86% | 2021-03-25 | 2024-11-21 |

| CVE-2020-7294 | Privilege Escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows authenticated user interface user to delete or download protected files via improper access controls in the REST interface. | [email protected] | 4.6 | 0.06% | 2020-09-15 | 2024-11-21 |
| CVE-2020-7293 | Privilege Escalation vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows authenticated user interface user with low permissions to change the system's root password via improper access controls in the user interface. | [email protected] | 9.0 | 0.10% | 2020-09-15 | 2024-11-21 |
| CVE-2020-7292 | Inappropriate Encoding for output context vulnerability in McAfee Web Gateway (MWG) prior to 9.2.1 allows a remote attacker to cause MWG to return an ambiguous redirect response via getting a user to click on a malicious URL. | [email protected] | 4.3 | 0.22% | 2020-07-15 | 2024-11-21 |
| CVE-2019-3638 | Reflected Cross Site Scripting vulnerability in Administrators web console in McAfee Web Gateway (MWG) 7.8.x prior to 7.8.2.13 allows remote attackers to collect sensitive information or execute commands with the MWG administrator's credentials via tricking the administrator to click on a carefully constructed malicious link. | [email protected] | 8.1 | 1.01% | 2019-09-12 | 2024-11-21 |
| CVE-2019-3644 | McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9517, potentially leading to a denial of service. This affects the scanning proxies. | [email protected] | 7.5 | 0.46% | 2019-09-11 | 2024-11-21 |
| CVE-2019-3643 | McAfee Web Gateway (MWG) earlier than 7.8.2.13 is vulnerable to a remote attacker exploiting CVE-2019-9511, potentially leading to a denial of service. This affects the scanning proxies. | [email protected] | 5.3 | 0.45% | 2019-09-11 | 2024-11-21 |
| CVE-2019-3639 | Clickjack vulnerability in Adminstrator web console in McAfee Web Gateway (MWG) 7.8.2.x prior to 7.8.2.12 allows remote attackers to conduct clickjacking attacks via a crafted web page that contains an iframe via does not send an X-Frame-Options HTTP header. | [email protected] | 7.1 | 0.27% | 2019-08-14 | 2024-11-21 |
| CVE-2019-3635 | Exfiltration of Data in McAfee Web Gateway (MWG) 7.8.2.x prior to 7.8.2.12 allows attackers to obtain sensitive data via crafting a complex webpage that will trigger the Web Gateway to block the user accessing an iframe. | [email protected] | 6.5 | 0.32% | 2019-08-14 | 2024-11-21 |
| CVE-2019-9518 | 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. | [email protected] | 7.5 | 3.65% | 2019-08-13 | 2025-01-14 |
| CVE-2019-9517 | 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. | [email protected] | 7.5 | 4.65% | 2019-08-13 | 2025-01-14 |
| CVE-2019-9516 | 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. | [email protected] | 6.5 | 2.13% | 2019-08-13 | 2025-01-14 |
| CVE-2019-9515 | 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. | [email protected] | 7.5 | 8.89% | 2019-08-13 | 2025-01-14 |
