The ABB Cylon Aspect BMS/BAS controller is vulnerable to session fixation, allowing an attacker to set a predefined PHPSESSID value. An attacker can leverage an unauthenticated reflected XSS vulnerability in jsonProxy.php to inject a crafted request, forcing the victim to adopt a fixated session.

### Summary An unsafe parsing logic of the URL from markdown can lead to arbitrary JavaScript code due to a bypass to the existing guards around the `javascript:` protocol scheme in the URL. ### Details The parsing logic implement at [https://github.com/nuxt-modules/mdc/blob/main/src/runtime/parser/utils/props.ts#L16](https://github.com/nuxt-modules/mdc/blob/main/src/runtime/parser/utils/props.ts#L16) maintains a deny-list approach to filtering potential malicious payload. It does so by matching protocol schemes like `javascript:` and others. Specifically, this is the code from the mdc library's parser that is not secure enough: ```js export const unsafeLinkPrefix = [ 'javascript:', 'data:text/html', 'vbscript:', 'data:text/javascript', 'data:text/vbscript', 'data:text/css', 'data:text/plain', 'data:text/xml' ] export const validateProp = (attribute: string, value: string) => { if (attribute.startsWith('on')) { return false } if (attribute === 'href' || ...

### Summary The better-auth `/api/auth/error` page was vulnerable to HTML injection, resulting in a reflected cross-site scripting (XSS) vulnerability. ### Details The value of `error` URL parameter was reflected as HTML on the error page: https://github.com/better-auth/better-auth/blob/05ada0b79dbcac93cc04ceb79b23ca598d07830c/packages/better-auth/src/api/routes/error.ts#L81 ### PoC https://demo.better-auth.com/api/auth/error?error=%3Cscript%3Ealert(1)%3C/script%3E  ### Impact An attacker who exploited this vulnerability by coercing a user to visit a specially-crafted URL could execute arbitrary JavaScript in the context of the user's browser. Because better-auth is a dependency of web applications, the impact of such a vulnerability is unknowable; it depends on the functionality of the application/site using better-auth. I have calculated the CVSS score assuming the hypothetical victim is an...

### Impact 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. ### Patches This vulnerability has been fixed in CKAN 2.10.7 and 2.11.2 ### Workarounds On versions prior to CKAN 2.10.7 and 2.11.2, site maintainers can restrict the file types supported for uploading using the [ckan.upload.user.mimetypes](https://docs.ckan.org/en/latest/maintaining/configuration.html#ckan-upload-user-mimetypes) / [ckan.upload.user.types](https://docs.ckan.org/en/latest/maintaining/configuration.html#ckan-upload-user-types) and [ckan.upload.group.mimetypes](https://docs.ckan.org/en/latest/maintaining/configuration.html#ckan-upload-group-mimetypes) / [ckan.upload.group.types](https://docs.ckan.or...

# Summary Django-Unicorn is vulnerable to python class pollution vulnerability, a new type of vulnerability categorized under [CWE-915](https://cwe.mitre.org/data/definitions/915.html). 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, so far we've found at least five ways of vulnerability exploitation, stably resulting in Cross-Site Scripting (XSS), Denial of Service (DoS), and Authentication Bypass attacks in almost every Django-Unicorn-based application. # Analysis of Vulnerable Function By taking a look at the vulnerable function `set_property_value` located at: `django_unicorn/views/action_parsers/utils.py`. You can observe the functionality is responsible for modifying a property value of an object. The propert...

### Impact We recently underwent Penetration Testing of OpenMRS by a third-party company. **Vulnerabilities were found, and fixes have been made and released.** We've released security updates that include critical fixes, and so, we strongly recommend upgrading affected modules. **This notice applies to _all_ OpenMRS instances.** The testers used the OpenMRS v3 Reference Application (O3 RefApp); however, their findings highlighted modules commonly used in older OpenMRS applications, including the O2 RefApp. ## Vulnerability Details - The issues uncovered included broken access control (e.g. inappropriate admin access), phishing vulnerability, and stored XSS (e.g. vulnerable passwords). - No vulnerabilities were found in the O3 frontend esm modules. - The Letter of Attestation from the penetration test is [available here](https://drive.google.com/file/d/1sBm4-FzLA8hSoM9wYknBfgEttBHyLvoU/view?usp=sharing) for your reference. - After the fixes were applied, the OpenMRS O3 RefApp met ...

DevDojo Voyager through version 1.8.0 is vulnerable to reflected XSS via /admin/compass. By manipulating an authenticated user to click on a link, arbitrary Javascript can be executed.

The rate of evolution has been glacial, but tools now understand cloud environments and can target Web applications.
