IBM Cognos Controller 11.0.0 and 11.0.1

could allow an authenticated user to upload insecure files, due to insufficient file type distinction.

IBM Cognos Controller 11.0.0 and 11.0.1

contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data.

IBM Cognos Controller 11.0.0 and 11.0.1

is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts.

Type Confusion in V8 in Google Chrome prior to 131.0.6778.108 allowed a remote attacker to potentially exploit object corruption via a crafted HTML page. (Chromium security severity: High)

An issue in aedes v0.51.2 allows attackers to cause a Denial of Service(DoS) via a crafted request.

An issue in mochiMQTT v2.6.3 allows attackers to cause a Denial of Service (DoS) via a crafted request.

IBM Cognos Controller 11.0.0 and 11.0.1

could allow an authenticated user with local access to bypass security allowing users to circumvent restrictions imposed on input fields.

IBM Cognos Controller 11.0.0 and 11.0.1

exposes server details that could allow an attacker to obtain information of the application environment to conduct further attacks.

Synapse is an open-source Matrix homeserver. Synapse before version 1.106 allows, by design, unauthenticated remote participants to trigger a download and caching of remote media from a remote homeserver to the local media repository. Such content then also becomes available for download from the local homeserver in an unauthenticated way. The implication is that unauthenticated remote adversaries can use this functionality to plant problematic content into the media repository. Synapse 1.106 introduces a partial mitigation in the form of new endpoints which require authentication for media downloads. The unauthenticated endpoints will be frozen in a future release, closing the attack vector.

Synapse is an open-source Matrix homeserver. Synapse versions before 1.106 are vulnerable to a disk fill attack, where an unauthenticated adversary can induce Synapse to download and cache large amounts of remote media. The default rate limit strategy is insufficient to mitigate this. This can lead to a denial of service, ranging from further media uploads/downloads failing to completely unavailability of the Synapse process, depending on how Synapse was deployed. Synapse 1.106 introduces a new "leaky bucket" rate limit on remote media downloads to reduce the amount of data a user can request at a time. This does not fully address the issue, but does limit an unauthenticated user's ability to request large amounts of data to be cached.
