Using crafted public RSA keys which are not compliant with SP 800-56B can cause a small memory leak when encrypting and verifying payloads. An attacker can leverage this flaw to gradually erode available memory to the point where the host crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service.
## Summary and impact [`GoogleOAuthenticator.hosted_domain`] is used to restrict what Google accounts can be authorized to access a JupyterHub. The restriction _is intended_ to ensure Google accounts are part of one or more Google organizations/workspaces verified to control specified domain(s). The vulnerability is that the actual restriction has been to Google accounts with emails ending with the domain. Such accounts could have been created by anyone which at one time was able to read an email associated with the domain. This was described by Dylan Ayrey (@dxa4481) in this [blog post] from 15th December 2023. ## Remediation Upgrade to `oauthenticator>=16.3.0` or restrict who can login another way, such as [`allowed_users`] or [`allowed_google_groups`]. [`GoogleOAuthenticator.hosted_domain`]: https://oauthenticator.readthedocs.io/en/latest/reference/api/gen/oauthenticator.google.html#oauthenticator.google.GoogleOAuthenticator.hosted_domain [`allowed_users`]: https://oauthenticat...
Moby is an open source container framework originally developed by Docker Inc. as Docker. It is a key component of Docker Engine, Docker Desktop, and other distributions of container tooling or runtimes. As a batteries-included container runtime, Moby comes with a built-in networking implementation that enables communication between containers, and between containers and external resources. Moby's networking implementation allows for creating and using many networks, each with their own subnet and gateway. This feature is frequently referred to as custom networks, as each network can have a different driver, set of parameters, and thus behaviors. When creating a network, the `--internal` flag is used to designate a network as _internal_. The `internal` attribute in a docker-compose.yml file may also be used to mark a network _internal_, and other API clients may specify the `internal` parameter as well. When containers with networking are created, they are assigned unique network int...
### Impact A user enumeration attack is possible. ### Affected versions Umbraco 10 with access to the native login screen ### Patches This is fixed in 10.8.5 ### Workarounds Disabling the native login screen, by exclusively use external logins.
### Summary deserializing json data using `qiskit_ibm_runtime.RuntimeDecoder` can be made to execute arbitrary code given a correctly formatted input string ### Details `RuntimeDecoder` is supposed to be able to deserialize JSON strings containing various special types encoded via `RuntimeEncoder`. However, one can structure a malicious payload to cause the decoder to spawn a subprocess and execute arbitrary code, exploiting this block of code: https://github.com/Qiskit/qiskit-ibm-runtime/blob/16e90f475e78a9d2ae77daa139ef750cfa84ca82/qiskit_ibm_runtime/utils/json.py#L156-L159 ### PoC ```python malicious_data = { "__type__": "settings", "__module__": "subprocess", "__class__": "Popen", "__value__": { "args": ["echo", "hi"] }, } json_str = json.dumps(malicious_data) _ = json.loads(json_str, cls=qiskit_ibm_runtime.RuntimeDecoder) # prints "hi" to the terminal ``` (where obviously "echo hi" can be replaced with something much more malicious) notably the ...
### Summary An `eval()` method exists `Options._get_program_inputs`. This is bad in any case, but especially bad because `Options` are also used server side, so this has the potential to expose arbitrary code injection in runtime containers, now or at a later time. ### Details https://github.com/Qiskit/qiskit-ibm-runtime/blob/da94a42060f1a22e6f306227deb45b70e0075723/qiskit_ibm_runtime/options/options.py#L140 ### PoC A local exploit would be something like ```python from qiskit import transpiler class BadActor(transpiler.CouplingMap): def __str__(self): return "print('external code')" ``` Where `print("external code")` can be any arbitrary python code string. Then if you did a normal workflow and used a specifically constructed `CouplingMap` subclass like `BadActor` above: ```python from qiskit_ibm_runtime import QiskitRuntimeService, Session, Options, Sampler from qiskit import QuantumCircuit cmap = BadActor.from_line(42) service = QiskitRuntimeService() options ...
Spring Authorization Server versions 1.0.0 - 1.0.5, 1.1.0 - 1.1.5, 1.2.0 - 1.2.2 and older unsupported versions are susceptible to a PKCE Downgrade Attack for Confidential Clients. Specifically, an application is vulnerable when a Confidential Client uses PKCE for the Authorization Code Grant. An application is not vulnerable when a Public Client uses PKCE for the Authorization Code Grant.
## Summary `jupyter-server-proxy` is used to expose ports local to a Jupyter server listening to web traffic to the Jupyter server's _authenticated users_ by proxying web requests and websockets. Dependent packages ([partial list](https://www.wheelodex.org/projects/jupyter-server-proxy/rdepends/)) also use `jupyter-server-proxy` to expose other popular interactive applications (such as [RStudio](https://github.com/jupyterhub/jupyter-rsession-proxy), [Linux Desktop via VNC](https://github.com/jupyterhub/jupyter-remote-desktop-proxy), [Code Server](https://github.com/betatim/vscode-binder), [Panel](https://github.com/holoviz/jupyter-panel-proxy), etc) along with the Jupyter server. This feature is commonly used in hosted environments (such as a JupyterHub) to expose non-Jupyter interactive frontends or APIs to the user. `jupyter-server-proxy` did not check user authentication appropriately when proxying websockets, allowing unauthenticated access to anyone who had network access to the...
### Summary A stored cross-site scripting (XSS) vulnerability exists that enables an authenticated administrator with workspace-level privileges to store a JavaScript payload in the GeoServer catalog that will execute in the context of another user's browser when viewed in the GWC Demos Page. Access to the GWC Demos Page is available to all users although data security may limit users' ability to trigger the XSS. ### Impact If an attacker can control a script that is executed in the victim's browser, then they can typically fully compromise that user. Amongst other things, the attacker can: 1 .Perform any action within the application that the user can perform. 2. View any information that the user is able to view. 3. Modify any information that the user is able to modify. 4. Initiate interactions with other application users, including malicious attacks, that will appear to originate from the initial victim user. ### References https://github.com/GeoWebCache/geowebcache/issues/117...
