Title
Maliciously crafted remote URLs could lead to credential leak in GitHub Desktop
Summary
GitHub Desktop is an open-source Electron-based GitHub app designed for git development. An attacker convincing a user to clone a repository directly or through a submodule can allow the attacker access to the user's credentials through the use of maliciously crafted remote URL. GitHub Desktop relies on Git to perform all network related operations (such as cloning, fetching, and pushing). When a user attempts to clone a repository GitHub Desktop will invoke `git clone` and when Git encounters a remote which requires authentication it will request the credentials for that remote host from GitHub Desktop using the git-credential protocol. Using a maliciously crafted URL it's possible to cause the credential request coming from Git to be misinterpreted by Github Desktop such that it will send credentials for a different host than the host that Git is currently communicating with thereby allowing for secret exfiltration. GitHub username and OAuth token, or credentials for other Git remote hosts stored in GitHub Desktop could be improperly transmitted to an unrelated host. Users should update to GitHub Desktop 3.4.12 or greater which fixes this vulnerability. Users who suspect they may be affected should revoke any relevant credentials.

"value": "GitHub Desktop es una aplicaci\u00f3n de GitHub de c\u00f3digo abierto basada en Electron dise\u00f1ada para el desarrollo de Git. Un atacante que convenza a un usuario de clonar un repositorio directamente o a trav\u00e9s de un subm\u00f3dulo puede permitirle acceder a las credenciales del usuario mediante el uso de una URL remota creada con fines malintencionados. GitHub Desktop depende de Git para realizar todas las operaciones relacionadas con la red (como clonar, obtener y enviar). Cuando un usuario intenta clonar un repositorio, GitHub Desktop invocar\u00e1 `git clone` y cuando Git encuentre un host remoto que requiera autenticaci\u00f3n, solicitar\u00e1 las credenciales para ese host remoto de GitHub Desktop utilizando el protocolo git-credential. Si se utiliza una URL creada con fines malintencionados, es posible hacer que Github Desktop malinterprete la solicitud de credenciales que proviene de Git, de modo que env\u00ede las credenciales para un host diferente al host con el que Git se est\u00e1 comunicando actualmente, lo que permite la exfiltraci\u00f3n secreta. El nombre de usuario y el token OAuth de GitHub, o las credenciales de otros hosts remotos de Git almacenados en GitHub Desktop, podr\u00edan transmitirse incorrectamente a un host no relacionado. Los usuarios deben actualizar a GitHub Desktop 3.4.12 o una versi\u00f3n posterior, que corrige esta vulnerabilidad. Los usuarios que sospechen que pueden verse afectados deben revocar las credenciales pertinentes."

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
