CVE-2023-24069 4 Apple, Linux, Microsoft and 1 more 4 Macos, Linux Kernel, Windows and 1 more 2024-06-04 3.3 Low
Signal Desktop before 6.2.0 on Windows, Linux, and macOS allows an attacker to obtain potentially sensitive attachments sent in messages from the attachments.noindex directory. Cached attachments are not effectively cleared. In some cases, even after a self-initiated file deletion, an attacker can still recover the file if it was previously replied to in a conversation. (Local filesystem access is needed by the attacker.) NOTE: the vendor disputes the relevance of this finding because the product is not intended to protect against adversaries with this degree of local access.
CVE-2023-24068 4 Apple, Linux, Microsoft and 1 more 4 Macos, Linux Kernel, Windows and 1 more 2024-05-17 7.8 High
Signal Desktop before 6.2.0 on Windows, Linux, and macOS allows an attacker to modify conversation attachments within the attachments.noindex directory. Client mechanisms fail to validate modifications of existing cached files, resulting in an attacker's ability to insert malicious code into pre-existing attachments or replace them completely. A threat actor can forward the existing attachment in the corresponding conversation to external groups, and the name and size of the file will not change, allowing the malware to masquerade as another file. NOTE: the vendor disputes the relevance of this finding because the product is not intended to protect against adversaries with this degree of local access.
CVE-2019-9970 1 Signal 2 Private Messenger, Signal-desktop 2022-04-07 N/A
Open Whisper Signal (aka Signal-Desktop) through 1.23.1 and the Signal Private Messenger application through 4.35.3 for Android are vulnerable to an IDN homograph attack when displaying messages containing URLs. This occurs because the application produces a clickable link even if (for example) Latin and Cyrillic characters exist in the same domain name, and the available font has an identical representation of characters from different alphabets.
CVE-2019-19954 2 Microsoft, Signal 2 Windows, Signal-desktop 2020-08-24 7.3 High
Signal Desktop before 1.29.1 on Windows allows local users to gain privileges by creating a Trojan horse %SYSTEMDRIVE%\node_modules\.bin\wmic.exe file.
CVE-2018-14023 1 Signal 1 Signal-desktop 2018-10-15 N/A
Open Whisper Signal (aka Signal-Desktop) before 1.15.0-beta.10 allows information leakage.
CVE-2018-11101 1 Signal 1 Signal-desktop 2018-06-19 N/A
Open Whisper Signal (aka Signal-Desktop) through 1.10.1 allows XSS via a resource location specified in an attribute of a SCRIPT, IFRAME, or IMG element, leading to JavaScript execution after a reply, a different vulnerability than CVE-2018-10994. The attacker needs to send HTML code directly as a message, and then reply to that message to trigger this vulnerability. The Signal-Desktop software fails to sanitize specific HTML elements that can be used to inject HTML code into remote chat windows when replying to an HTML message. Specifically the IMG and IFRAME elements can be used to include remote or local resources. For example, the use of an IFRAME element enables full code execution, allowing an attacker to download/upload files, information, etc. The SCRIPT element was also found to be injectable. On the Windows operating system, the CSP fails to prevent remote inclusion of resources via the SMB protocol. In this case, remote execution of JavaScript can be achieved by referencing the script on an SMB share within an IFRAME element, for example: <IFRAME src=\\DESKTOP-XXXXX\Temp\test.html> and then replying to it. The included JavaScript code is then executed automatically, without any interaction needed from the user. The vulnerability can be triggered in the Signal-Desktop client by sending a specially crafted message and then replying to it with any text or content in the reply (it doesn't matter).
CVE-2018-10994 1 Signal 1 Signal-desktop 2018-06-18 N/A
js/views/message_view.js in Open Whisper Signal (aka Signal-Desktop) before 1.10.1 allows XSS via a URL.
