CVSS: 9.9EPSS: 0%CPEs: 2EXPL: 1CVE-2023-43651 – Remote code execution on the host system via MongoDB shell in jumpserver
https://notcve.org/view.php?id=CVE-2023-43651
JumpServer is an open source bastion host. An authenticated user can exploit a vulnerability in MongoDB sessions to execute arbitrary commands, leading to remote code execution. This vulnerability may further be leveraged to gain root privileges on the system. Through the WEB CLI interface provided by the koko component, a user logs into the authorized mongoDB database and exploits the MongoDB session to execute arbitrary commands. This vulnerability has been addressed in versions 2.28.20 and 3.7.1. • https://github.com/jumpserver/jumpserver/security/advisories/GHSA-4r5x-x283-wm96 • CWE-94: Improper Control of Generation of Code ('Code Injection') •
CVSS: 8.2EPSS: 0%CPEs: 2EXPL: 1CVE-2023-43650 – Non-MFA account takeover via brute-force attack on weak password reset code in jumpserver
https://notcve.org/view.php?id=CVE-2023-43650
JumpServer is an open source bastion host. The verification code for resetting user's password is vulnerable to brute-force attacks due to the absence of rate limiting. JumpServer provides a feature allowing users to reset forgotten passwords. Affected users are sent a 6-digit verification code, ranging from 000000 to 999999, to facilitate the password reset. Although the code is only available in 1 minute, this window potentially allows for up to 1,000,000 validation attempts. • https://github.com/jumpserver/jumpserver/security/advisories/GHSA-mwx4-8fwc-2xvw • CWE-640: Weak Password Recovery Mechanism for Forgotten Password •
CVSS: 9.1EPSS: 0%CPEs: 2EXPL: 1CVE-2023-43652 – Non-MFA account takeover via using only SSH public key to login in jumpserver
https://notcve.org/view.php?id=CVE-2023-43652
JumpServer is an open source bastion host. As an unauthenticated user, it is possible to authenticate to the core API with a username and an SSH public key without needing a password or the corresponding SSH private key. An SSH public key should be considered public knowledge and should not used as an authentication secret alone. JumpServer provides an API for the KoKo component to validate user private key logins. This API does not verify the source of requests and will generate a personal authentication token. • https://github.com/jumpserver/jumpserver/security/advisories/GHSA-fr8h-xh5x-r8g9 • CWE-862: Missing Authorization •
CVSS: 8.9EPSS: 0%CPEs: 1EXPL: 1CVE-2023-42819 – Path traversal in Jumpserver
https://notcve.org/view.php?id=CVE-2023-42819
JumpServer is an open source bastion host. Logged-in users can access and modify the contents of any file on the system. A user can use the 'Job-Template' menu and create a playbook named 'test'. Get the playbook id from the detail page, like 'e0adabef-c38f-492d-bd92-832bacc3df5f'. An attacker can exploit the directory traversal flaw using the provided URL to access and retrieve the contents of the file. • https://github.com/C1ph3rX13/CVE-2023-42819 https://github.com/jumpserver/jumpserver/commit/d0321a74f1713d031560341c8fd0a1859e6510d8 https://github.com/jumpserver/jumpserver/security/advisories/GHSA-ghg2-2whp-6m33 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 8.2EPSS: 0%CPEs: 2EXPL: 1CVE-2023-42820 – Random seed leakage in Jumpserver
https://notcve.org/view.php?id=CVE-2023-42820
JumpServer is an open source bastion host. This vulnerability is due to exposing the random number seed to the API, potentially allowing the randomly generated verification codes to be replayed, which could lead to password resets. If MFA is enabled users are not affect. Users not using local authentication are also not affected. Users are advised to upgrade to either version 2.28.19 or to 3.6.5. • https://github.com/C1ph3rX13/CVE-2023-42820 https://github.com/jumpserver/jumpserver/commit/42337f0d00b2a8d45ef063eb5b7deeef81597da5 https://github.com/jumpserver/jumpserver/security/advisories/GHSA-7prv-g565-82qp • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
