CVE-2021-22926 5 Haxx, Netapp, Oracle and 2 more 26 Curl, Active Iq Unified Manager, Clustered Data Ontap and 23 more 2024-11-21 7.5 High
libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use the macOS native TLS library Secure Transport, an application can ask for the client certificate by name or with a file name - using the same option. If the name exists as a file, it will be used instead of by name.If the appliction runs with a current working directory that is writable by other users (like `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and thereby trick the application to use the file based cert instead of the one referred to by name making libcurl send the wrong client certificate in the TLS connection handshake.
CVE-2021-22924 8 Debian, Fedoraproject, Haxx and 5 more 55 Debian Linux, Fedora, Libcurl and 52 more 2024-11-21 3.7 Low
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
CVE-2021-22909 1 Ui 2 Edgemax Edgerouter, Edgemax Edgerouter Firmware 2024-11-21 7.5 High
A vulnerability found in EdgeMAX EdgeRouter V2.0.9 and earlier could allow a malicious actor to execute a man-in-the-middle (MitM) attack during a firmware update. This vulnerability is fixed in EdgeMAX EdgeRouter V2.0.9-hotfix.1 and later.
CVE-2021-22897 5 Haxx, Netapp, Oracle and 2 more 30 Curl, Cloud Backup, H300e and 27 more 2024-11-21 5.3 Medium
curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transport security significantly.
CVE-2021-22895 2 Debian, Nextcloud 2 Debian Linux, Desktop 2024-11-21 5.9 Medium
Nextcloud Desktop Client before 3.3.1 is vulnerable to improper certificate validation due to lack of SSL certificate verification when using the "Register with a Provider" flow.
CVE-2021-22511 1 Microfocus 1 Application Automation Tools 2024-11-21 6.5 Medium
Improper Certificate Validation vulnerability in Micro Focus Application Automation Tools Plugin - Jenkins plugin. The vulnerability affects version 6.7 and earlier versions. The vulnerability could allow unconditionally disabling of SSL/TLS certificates.
CVE-2021-22278 2 Abb, Hitachienergy 2 Update Manager, Pcm600 2024-11-21 6.7 Medium
A certificate validation vulnerability in PCM600 Update Manager allows attacker to get unwanted software packages to be installed on computer which has PCM600 installed.
CVE-2021-22218 1 Gitlab 1 Gitlab 2024-11-21 2.6 Low
All versions of GitLab CE/EE starting from 12.8 before 13.10.5, all versions starting from 13.11 before 13.11.5, and all versions starting from 13.12 before 13.12.2 were affected by an issue in the handling of x509 certificates that could be used to spoof author of signed commits.
CVE-2021-22189 1 Gitlab 1 Gitlab 2024-11-21 5.9 Medium
Starting with version 13.7 the Gitlab CE/EE editions were affected by a security issue related to the validation of the certificates for the Fortinet OTP that could result in authentication issues.
CVE-2021-22138 1 Elastic 1 Logstash 2024-11-21 3.7 Low
In Logstash versions after 6.4.0 and before 6.8.15 and 7.12.0 a TLS certificate validation flaw was found in the monitoring feature. When specifying a trusted server CA certificate Logstash would not properly verify the certificate returned by the monitoring server. This could result in a man in the middle style attack against the Logstash monitoring data.
CVE-2021-22131 1 Fortinet 1 Fortitoken Mobile 2024-11-21 6.4 Medium
A improper validation of certificate with host mismatch in Fortinet FortiTokenAndroid version 5.0.3 and below, Fortinet FortiTokeniOS version 5.2.0 and below, Fortinet FortiTokenWinApp version 4.0.3 and below allows attacker to retrieve information disclosed via man-in-the-middle attacks.
CVE-2021-21571 1 Dell 256 Alienware M15 R6, Alienware M15 R6 Firmware, Chengming 3990 and 253 more 2024-11-21 5.9 Medium
Dell UEFI BIOS https stack leveraged by the Dell BIOSConnect feature and Dell HTTPS Boot feature contains an improper certificate validation vulnerability. A remote unauthenticated attacker may exploit this vulnerability using a person-in-the-middle attack which may lead to a denial of service and payload tampering.
CVE-2021-21559 1 Dell 1 Emc Networker 2024-11-21 7.1 High
Dell EMC NetWorker, versions 18.x, 19.1.x, 19.2.x 19.3.x, 19.4, and 19.4.0.1 contain an Improper Certificate Validation vulnerability in the client (NetWorker Management Console) components which uses SSL encrypted connection in order to communicate with the application server. An unauthenticated attacker in the same network collision domain as the NetWorker Management Console client could potentially exploit this vulnerability to perform man-in-the-middle attacks to intercept and tamper the traffic between the client and the application server.
CVE-2021-21385 1 Mifos 1 Mifos-mobile 2024-11-21 8.8 High
Mifos-Mobile Android Application for MifosX is an Android Application built on top of the MifosX Self-Service platform. Mifos-Mobile before commit e505f62 disables HTTPS hostname verification of its HTTP client. Additionally it accepted any self-signed certificate as valid. Hostname verification is an important part when using HTTPS to ensure that the presented certificate is valid for the host. Disabling it can allow for man-in-the-middle attacks. Accepting any certificate, even self-signed ones allows man-in-the-middle attacks. This problem is fixed in mifos-mobile commit e505f62.
CVE-2021-21374 1 Nim-lang 1 Nim 2024-11-21 8.1 High
Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS without full verification of the SSL/TLS certificate due to the default setting of httpClient. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution.
CVE-2021-21373 1 Nim-lang 1 Nim 2024-11-21 7.5 High
Nimble is a package manager for the Nim programming language. In Nim release versions before versions 1.2.10 and 1.4.4, "nimble refresh" fetches a list of Nimble packages over HTTPS by default. In case of error it falls back to a non-TLS URL http://irclogs.nim-lang.org/packages.json. An attacker able to perform MitM can deliver a modified package list containing malicious software packages. If the packages are installed and used the attack escalates to untrusted code execution.
