xml2rfc has file inclusion irregularities

Version [3.12.0](https://github.com/ietf-tools/xml2rfc/blob/main/CHANGELOG.md#3120---2021-12-08) changed `xml2rfc` so that it would not access local files without the presence of its new `--allow-local-file-access` flag. This prevented XML External Entity (XXE) injection attacks with `xinclude` and XML entity references. It was discovered that `xml2rfc` does not respect `--allow-local-file-access` when a local file is specified as `src` in `artwork` or `sourcecode` elements. Furthermore, XML entity references can include any file inside the source dir and below without using the `--allow-local-file-access` flag. The `xml2rfc <= 3.26.0` beh

vLLM using built-in hash() from Python 3.12 leads to predictable hash collisions in vLLM prefix cache

vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. Maliciously constructed statements can lead to hash collisions, resulting in cache reuse, which can interfere with subsequent responses and cause unintended behavior. Prefix caching makes use of Python's built-in hash() function. As of Python 3.12, the behavior of hash(None) has changed to be a predictable constant value. This makes it more feasible that someone could try exploit hash collisions. The impact of a collision would be using cache that was generated using different content. Given knowledge of prompts in use and predictable hashing behavior, someo

Mitmweb API Authentication Bypass Using Proxy Server

mitmproxy is a interactive TLS-capable intercepting HTTP proxy for penetration testers and software developers and mitmweb is a web-based interface for mitmproxy. In mitmweb 11.1.1 and below, a malicious client can use mitmweb's proxy server (bound to `*:8080` by default) to access mitmweb's internal API (bound to `127.0.0.1:8081` by default). In other words, while the cannot access the API directly, they can access the API through the proxy. An attacker may be able to escalate this SSRF-style access to remote code execution. The mitmproxy and mitmdump tools are unaffected. Only mitmweb is affected. This vulnerability has been fixed in mitmpr

Stored Cross-Site Scripting (XSS) in MobSF

Mobile Security Framework (MobSF) is an automated, all-in-one mobile application (Android/iOS/Windows) pen-testing, malware analysis and security assessment framework. According to Apple's documentation for bundle ID's, it must contain only alphanumeric characters (A–Z, a–z, and 0–9), hyphens (-), and periods (.). However, an attacker can manually modify this value in the `Info.plist` file and add special characters to the `<key>CFBundleIdentifier</key>` value. The `dynamic_analysis.html` file does not sanitize the received bundle value from Corellium and as a result, it is possible to break the HTML context and achieve Stored XSS. This issue

Partial Denial of Service (DoS) in MobSF

Mobile Security Framework (MobSF) is an automated, all-in-one mobile application (Android/iOS/Windows) pen-testing, malware analysis and security assessment framework. According to Apple's documentation for bundle ID's, it must contain only alphanumeric characters (A–Z, a–z, and 0–9), hyphens (-), and periods (.). However, an attacker can manually modify this value in the `Info.plist` file and add special characters to the `<key>CFBundleIdentifier</key>` value. When the application parses the wrong characters in the bundle ID, it encounters an error. As a result, it will not display content and will throw a 500 error instead. The only way to

Local Privilege Escalation in MobSF

Mobile Security Framework (MobSF) is an automated, all-in-one mobile application (Android/iOS/Windows) pen-testing, malware analysis and security assessment framework. A local user with minimal privileges is able to make use of an access token for materials for scopes which it should not be accepted. This issue has been addressed in version 4.3.1 and all users are advised to upgrade. There are no known workarounds for this vulnerability.

XSS vector in user uploaded images in group/org and user profiles in ckan

CKAN is an open-source DMS (data management system) for powering data hubs and data portals. Using a specially crafted file, a user could potentially upload a file containing code that when executed could send arbitrary requests to the server. If that file was opened by an administrator, it could lead to escalation of privileges of the original submitter or other malicious actions. Users must have been registered to the site to exploit this vulnerability. This vulnerability has been fixed in CKAN 2.10.7 and 2.11.2. Users are advised to upgrade. On versions prior to CKAN 2.10.7 and 2.11.2, site maintainers can restrict the file types supported

Django-Unicorn Class Pollution Vulnerability, Leading to XSS, DoS and Authentication Bypass

Django-Unicorn adds modern reactive component functionality to Django templates. Affected versions of Django-Unicorn are vulnerable to python class pollution vulnerability. The vulnerability arises from the core functionality `set_property_value`, which can be remotely triggered by users by crafting appropriate component requests and feeding in values of second and third parameter to the vulnerable function, leading to arbitrary changes to the python runtime status. With this finding at least five ways of vulnerability exploitation have been observed, stably resulting in Cross-Site Scripting (XSS), Denial of Service (DoS), and Authentication

URL parser allowed square brackets in domain names

The Python standard library functions `urllib.parse.urlsplit` and `urlparse` accepted domain names that included square brackets which isn't valid according to RFC 3986. Square brackets are only meant to be used as delimiters for specifying IPv6 and IPvFuture hosts in URLs. This could result in differential parsing across the Python URL parser and other specification-compliant URL parsers.

vLLM allows a malicious model RCE by torch.load in hf_model_weights_iterator

vLLM is a library for LLM inference and serving. vllm/model_executor/weight_utils.py implements hf_model_weights_iterator to load the model checkpoint, which is downloaded from huggingface. It uses the torch.load function and the weights_only parameter defaults to False. When torch.load loads malicious pickle data, it will execute arbitrary code during unpickling. This vulnerability is fixed in v0.7.0.

ASTEVAL Vulnerable to Maliciously Crafted Format Strings Leading to Sandbox Escape

ASTEVAL is an evaluator of Python expressions and statements. Prior to version 1.0.6, if an attacker can control the input to the `asteval` library, they can bypass asteval's restrictions and execute arbitrary Python code in the context of the application using the library. The vulnerability is rooted in how `asteval` performs handling of `FormattedValue` AST nodes. In particular, the `on_formattedvalue` value uses the dangerous format method of the str class. The code allows an attacker to manipulate the value of the string used in the dangerous call `fmt.format(__fstring__=val)`. This vulnerability can be exploited to access protected attri

ASTEVAL Allows Malicious Tampering of Exposed AST Nodes Leads to Sandbox Escape

### Summary If an attacker can control the input to the asteval library, they can bypass its safety restrictions and execute arbitrary Python code within the application's context. ### Details The vulnerability is rooted in how `asteval` performs attribute access verification. In particular, the [`on_attribute`](https://github.com/lmfit/asteval/blob/8d7326df8015cf6a57506b1c2c167a1c3763e090/asteval/asteval.py#L565) node handler prevents access to attributes that are either present in the `UNSAFE_ATTRS` list or are formed by names starting and ending with `__`, as shown in the code snippet below: ```py def on_attribute(self, node): # (

try/except* clauses could allow bypass RestrictedPython via type confusion bug in the CPython interpreter

RestrictedPython is a tool that helps to define a subset of the Python language which allows to provide a program input into a trusted environment. Via a type confusion bug in versions of the CPython interpreter starting in 3.11 and prior to 3.13.2 when using `try/except*`, RestrictedPython starting in version 6.0 and prior to version 8.0 could be bypassed. The issue is patched in version 8.0 of RestrictedPython by removing support for `try/except*` clauses. No known workarounds are available.
