![]() There are currently no known workarounds. Version 6.4.12 contains a patch for this issue. So this does not generally result in any privilege escalation or increase in information access, only an additional, unintended means by which the files could be accessed. Such contexts also necessarily have full access to the server and therefore execution permissions, which also generally grants access to all the same files. `~/.ssh` while serving $HOME), then any authenticated requests could access files if their names are guessable. But if a server's root directory contains sensitive files whose only protection from the server is being hidden (e.g. Because fully authenticated requests are required, this is of relatively low impact. This could lead to notebook configurations allowing authenticated access to files that may reasonably be expected to be disallowed. hidden files were 'hidden' but not 'inaccessible'). Prior to version 6.4.12, authenticated requests to the notebook server with `ContentsManager.allow_hidden = False` only prevented listing the contents of hidden directories, not accessing individual hidden files or files in hidden directories (i.e. Jupyter Notebook is a web-based notebook environment for interactive computing. ssh/authorized_keys, allowing a malicious user to read potentially sensitive data and possibly gain control of the impacted system. This token can be used along with the REST API to interact with Jupyter services/notebooks such as modifying or overwriting critical files, such as. While this requires an authenticated user session, this URL can be used from a cross-site scripting payload or from a hooked or otherwise compromised browser to leak this access token to a malicious third party. Prior to version 1.17.1, if notebook server is started with a value of `root_dir` that contains the starting user's home directory, then the underlying REST API can be used to leak the access token assigned at start time by guessing/brute forcing the PID of the jupyter server. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter Notebook. Jupyter Server provides the backend (i.e. As a workaround, one may disable support for `curve25519-sha256` and key exchange algorithms. Version 2020.0.2 contains a patch for this issue. This allows an attacker who is able to eavesdrop on the communications to decrypt them. When establishing an SSH connection to a remote host, during the X25519 key exchange, the private key is generated with a weak random number generator whose seed can be brute forced. `System.Random` is not a cryptographically secure random number generator, it must therefore not be used for cryptographic purposes. In versions 2020.0.0.1, during an `X25519` key exchange, the client’s private key is generated with `System.Random`. SSH.NET is a Secure Shell (SSH) library for. ** DISPUTED ** FileZilla v3.59.0 allows attackers to obtain cleartext passwords of connected SSH or FTP servers via a memory dump.- NOTE: the vendor does not consider this a vulnerability. The Hashicorp go-getter library before 1.5.11 does not redact an SSH key from a URL query parameter. NOTE: WinRAR and Android RAR are unaffected. RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. An authenticated attacker could read arbitrary files from the underlying operating system of the scanner using a custom crafted compliance audit file without providing any valid SSH credentials.Ī missing permission check in Jenkins SSH Plugin 2.6.1 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified SSH server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.Ī cross-site request forgery (CSRF) vulnerability in Jenkins SSH Plugin 2.6.1 and earlier allows attackers to connect to an attacker-specified SSH server using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.Ī missing permission check in Jenkins SSH Plugin 2.6.1 and earlier allows attackers with Overall/Read permission to enumerate credentials IDs of credentials stored in Jenkins.
