CVSS: 8.4EPSS: 0%CPEs: 1EXPL: 0CVE-2024-34346 – Deno contains a permission escalation via open of privileged files with missing `--deny` flag
https://notcve.org/view.php?id=CVE-2024-34346
Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. The Deno sandbox may be unexpectedly weakened by allowing file read/write access to privileged files in various locations on Unix and Windows platforms. For example, reading `/proc/self/environ` may provide access equivalent to `--allow-env`, and writing `/proc/self/mem` may provide access equivalent to `--allow-all`. Users who grant read and write access to the entire filesystem may not realize that these access to these files may have additional, unintended consequences. The documentation did not reflect that this practice should be undertaken to increase the strength of the security sandbox. • https://github.com/denoland/deno/security/advisories/GHSA-23rx-c3g5-hv9w • CWE-863: Incorrect Authorization •
CVSS: 7.7EPSS: 0%CPEs: 1EXPL: 0CVE-2024-32477 – Race condition when flushing input stream leads to permission prompt bypass
https://notcve.org/view.php?id=CVE-2024-32477
Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. By using ANSI escape sequences and a race between `libc::tcflush(0, libc::TCIFLUSH)` and reading standard input, it's possible to manipulate the permission prompt and force it to allow an unsafe action regardless of the user input. Some ANSI escape sequences act as a info request to the master terminal emulator and the terminal emulator sends back the reply in the PTY channel. standard streams also use this channel to send and get data. For example the `\033[6n` sequence requests the current cursor position. These sequences allow us to append data to the standard input of Deno. • https://github.com/denoland/deno/security/advisories/GHSA-95cj-3hr2-7j5j • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-27936 – Deno interactive permission prompt spoofing via improper ANSI stripping
https://notcve.org/view.php?id=CVE-2024-27936
Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. Starting in version 1.32.1 and prior to version 1.41.0 of the deno library, maliciously crafted permission request can show the spoofed permission prompt by inserting a broken ANSI escape sequence into the request contents. Deno is stripping any ANSI escape sequences from the permission prompt, but permissions given to the program are based on the contents that contain the ANSI escape sequences. Any Deno program can spoof the content of the interactive permission prompt by inserting a broken ANSI code, which allows a malicious Deno program to display the wrong file path or program name to the user. Version 1.41.0 of the deno library contains a patch for the issue. • https://github.com/denoland/deno/commit/78d430103a8f6931154ddbbe19d36f3b8630286d https://github.com/denoland/deno/commit/7e6b94231290020b55f1d08fb03ea8132781abc5 https://github.com/denoland/deno/security/advisories/GHSA-m4pq-fv2w-6hrw • CWE-150: Improper Neutralization of Escape, Meta, or Control Sequences •
CVSS: 4.6EPSS: 0%CPEs: 1EXPL: 0CVE-2024-27932 – Deno's improper suffix match testing for DENO_AUTH_TOKENS
https://notcve.org/view.php?id=CVE-2024-27932
Deno is a JavaScript, TypeScript, and WebAssembly runtime. Starting in version 1.8.0 and prior to version 1.40.4, Deno improperly checks that an import specifier's hostname is equal to or a child of a token's hostname, which can cause tokens to be sent to servers they shouldn't be sent to. An auth token intended for `example[.]com` may be sent to `notexample[.]com`. Anyone who uses DENO_AUTH_TOKENS and imports potentially untrusted code is affected. Version 1.40.0 contains a patch for this issue Deno es un tiempo de ejecución de JavaScript, TypeScript y WebAssembly. • https://github.com/denoland/deno/blob/3f4639c330a31741b0efda2f93ebbb833f4f95bc/cli/auth_tokens.rs#L89 https://github.com/denoland/deno/commit/de23e3b60b066481cc390f459497d5bef42a899b https://github.com/denoland/deno/security/advisories/GHSA-5frw-4rwq-xhcr • CWE-20: Improper Input Validation •
CVSS: 5.8EPSS: 0%CPEs: 1EXPL: 0CVE-2024-27931 – Insufficient permission checking in `Deno.makeTemp*` APIs
https://notcve.org/view.php?id=CVE-2024-27931
Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. Insufficient validation of parameters in `Deno.makeTemp*` APIs would allow for creation of files outside of the allowed directories. This may allow the user to overwrite important files on the system that may affect other systems. A user may provide a prefix or suffix to a `Deno.makeTemp*` API containing path traversal characters. This is fixed in Deno 1.41.1. • https://github.com/denoland/deno/security/advisories/GHSA-hrqr-jv8w-v9jh • CWE-20: Improper Input Validation •
