Details

Ashlar-Vellum Cobalt CO File Parsing Type Confusion Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the parsing of CO files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25981.

Details

A type confusion bug in TypedArray prior to commit e6ed9c1a4b02dc219de1648f44cd808a56171b81 could have been used by a malicious attacker to execute arbitrary code via untrusted JavaScript. Note that this is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Hence, most React Native applications are not affected.

Details

The vulnerability allows any attacker to cause the PeerTube server to stop functioning, or in special cases send requests to arbitrary URLs (Blind SSRF). Attackers can send ActivityPub activities to PeerTube's "inbox" endpoint. By abusing the "Create Activity" functionality, it is possible to create crafted playlists which will cause either denial of service or an attacker-controlled blind SSRF.
