CVE-2024-12777 (GCVE-0-2024-12777)

Vulnerability from cvelistv5 – Published: 2025-03-20 10:11 – Updated: 2025-03-20 13:30
VLAI
Title
Denial of Service in aimhubio/aim
Summary
A vulnerability in aimhubio/aim version 3.25.0 allows for a denial of service through the misuse of the sshfs-client. The tracking server, which is single-threaded, can be made unresponsive by requesting it to connect to an unresponsive socket via sshfs. The lack of an additional timeout setting in the sshfs-client causes the server to hang for a significant amount of time, preventing it from responding to other requests.

CVE-2024-8062 (GCVE-0-2024-8062)

Vulnerability from cvelistv5 – Published: 2025-03-20 10:11 – Updated: 2025-03-20 15:23
VLAI
Title
Denial of Service in h2oai/h2o-3
Summary
A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service. The endpoint performs a `HEAD` request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controlled server that hangs, causing the application to block and become unresponsive to other requests.

CVE-2024-8061 (GCVE-0-2024-8061)

Vulnerability from cvelistv5 – Published: 2025-03-20 10:10 – Updated: 2025-10-15 12:49
VLAI
Title
Denial of Service in aimhubio/aim
Summary
In version 3.23.0 of aimhubio/aim, certain methods that request data from external servers do not have set timeouts, causing the server to wait indefinitely for a response. This can lead to a denial of service, as the tracking server does not respond to other requests while waiting. The issue arises in the client used by the `aim` tracking server to communicate with external resources, specifically in the `_run_read_instructions` method and similar calls without timeouts.

Vulnerability from github – Published: 2018-07-23 19:51 – Updated: 2024-09-16 22:34

Summary
Denial of service in django
Details

The verify_exists functionality in the URLField implementation in Django before 1.2.7 and 1.3.x before 1.3.1 relies on Python libraries that attempt access to an arbitrary URL with no timeout, which allows remote attackers to cause a denial of service (resource consumption) via a URL associated with (1) a slow response, (2) a completed TCP connection with no application data sent, or (3) a large amount of application data, a related issue to CVE-2011-1521.

VLAI
Summary
H2O Vulnerable to Denial of Service (DoS) via `HEAD` Request
Details

A vulnerability in the typeahead endpoint of h2oai/h2o-3 version 3.46.0 allows for a denial of service. The endpoint performs a HEAD request to verify the existence of a specified resource without setting a timeout. An attacker can exploit this by sending multiple requests to an attacker-controlled server that hangs, causing the application to block and become unresponsive to other requests.

Vulnerability from github – Published: 2025-03-20 12:32 – Updated: 2025-10-15 16:07
VLAI
Summary
Aim allows denial of service due to no timeouts for some tracking server endpoints
Details

In version 3.23.0 of aimhubio/aim, certain methods that request data from external servers do not have set timeouts, causing the server to wait indefinitely for a response. This can lead to a denial of service, as the tracking server does not respond to other requests while waiting. The issue arises in the client used by the aim tracking server to communicate with external resources, specifically in the _run_read_instructions method and similar calls without timeouts.

Summary
Aim vulnerable to Synchronous Access of Remote Resource without Timeout
Details

A vulnerability in aimhubio/aim version 3.25.0 allows for a denial of service through the misuse of the sshfs-client. The tracking server, which is single-threaded, can be made unresponsive by requesting it to connect to an unresponsive socket via sshfs. The lack of an additional timeout setting in the sshfs-client causes the server to hang for a significant amount of time, preventing it from responding to other requests.
