### Impact A prototype pollution vulnerability exists in versions 0.5.0 and earlier, wherein if you provide a policy name called `__proto__` you can override the Object prototype. For example: ``` const parse = require('content-security-policy-parser'); const x = parse("default-src 'self'; __proto__ foobar"); console.log('raw print:', x); console.log('toString:', x.toString()); ``` Outputs: ``` raw print: Array { 'default-src': [ "'self'" ] } toString: foobar ``` Whilst no gadget exists in this library, it is possible via other libraries expose functionality that enable RCE. It is customary to label prototype pollution vulnerabilities in this way. The most common effect of this is denial of service, as you can trivially overwrite properties. As the content security policy is provided in HTTP queries, it is incredibly likely that network exploitation is possible. ### Patches There has been a patch implemented a year ago (11 Feb 2024), but low uptake of patched versions has not b...

View CSAF 1. EXECUTIVE SUMMARY CVSS v4 8.7 ATTENTION: Exploitable remotely/low attack complexity Vendor: Schneider Electric Equipment: EcoStruxure Power Monitoring Expert Vulnerabilities: Path Traversal, Deserialization of Untrusted Data, Server-Side Request Forgery 2. RISK EVALUATION Successful exploitation of these vulnerabilities could allow a remote attacker to read arbitrary files from the target machine, or to access internal services directly. 3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS Schneider Electric reports the following versions of EcoStruxure Power Monitoring Expert are affected: EcoStruxure Power Monitoring Expert: Version 13.1 3.2 VULNERABILITY OVERVIEW 3.2.1 PATH TRAVERSAL CWE-22 Schneider Electric EcoStruxure Power Monitoring Expert contains a directory traversal vulnerability, which may enable remote code execution when an authenticated attacker with admin privileges uploads a malicious file over HTTP which then gets executed. Authentication is required to exploit th...

Deserialization of untrusted data in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.

Heap-based buffer overflow in Microsoft Teams allows an unauthorized attacker to execute code over a network.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** A race condition is triggered when the admin begins administering from the host system and not a guest or nested guest.

**According to the CVSS metric, the privilege required is none (PR:N) and user interaction is none (UI:N). What does that mean for this vulnerability?** An attacker doesn't require any privileges on the systems hosting the web services. Successful exploitation of this vulnerability could cause Remote Code Execution or Information Disclosure on web services that are parsing documents that contain a specially crafted metafile, without the involvement of a victim user.
