CVSS: 8.3EPSS: 0%CPEs: 2EXPL: 0CVE-2023-41039 – Sandbox escape via various forms of "format" in RestrictedPython
https://notcve.org/view.php?id=CVE-2023-41039
30 Aug 2023 — RestrictedPython is a restricted execution environment for Python to run untrusted code. Python's "format" functionality allows someone controlling the format string to "read" all objects accessible through recursive attribute lookup and subscription from objects he can access. This can lead to critical information disclosure. With `RestrictedPython`, the format functionality is available via the `format` and `format_map` methods of `str` (and `unicode`) (accessed either via the class or its instances) and ... • https://github.com/zopefoundation/RestrictedPython/commit/4134aedcff17c977da7717693ed89ce56d54c120 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 9.9EPSS: 0%CPEs: 3EXPL: 0CVE-2023-37271 – RestrictedPython vulnerable to arbitrary code execution via stack frame sandbox escape
https://notcve.org/view.php?id=CVE-2023-37271
11 Jul 2023 — RestrictedPython is a tool that helps to define a subset of the Python language which allows users to provide a program input into a trusted environment. RestrictedPython does not check access to stack frames and their attributes. Stack frames are accessible within at least generators and generator expressions, which are allowed inside RestrictedPython. Prior to versions 6.1 and 5.3, an attacker with access to a RestrictedPython environment can write code that gets the current stack frame in a generator and... • https://github.com/zopefoundation/RestrictedPython/commit/c8eca66ae49081f0016d2e1f094c3d72095ef531 • CWE-913: Improper Control of Dynamically-Managed Code Resources •
