The average higher education institution is getting hit once a week now, and as one University of Oregon attack shows, the sector often lacks the resources to keep pace.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a critical security flaw impacting Fortinet products to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2024-23113 (CVSS score: 9.8), relates to cases of remote code execution that affects FortiOS, FortiPAM, FortiProxy, and FortiWeb. "A

Mozilla has revealed that a critical security flaw impacting Firefox and Firefox Extended Support Release (ESR) has come under active exploitation in the wild. The vulnerability, tracked as CVE-2024-9680, has been described as a use-after-free bug in the Animation timeline component. "An attacker was able to achieve code execution in the content process by exploiting a use-after-free in

The Elliptic package 6.5.5 for Node.js for EDDSA implementation does not perform the required check if the signature proof(s) is within the bounds of the order n of the base point of the elliptic curve, leading to signature malleability. Namely, the `verify` function in `lib/elliptic/eddsa/index.js` omits `sig.S().gte(sig.eddsa.curve.n) || sig.S().isNeg()` validation. This vulnerability could have a security-relevant impact if an application relies on the uniqueness of a signature.

### Summary The app uses sha-256 as the hash for passwords. The app should switch to bcrypt. ### Details SHA-256 is a message digest hash, and not classified as secure for password hashing. Message digest hashes are designed to be fast, while password hashing mechanisms are designed with certain cryptographic properties (e.g. slow) to protect against vulnerabilities.

An information disclosure vulnerability exists in open-webui version 0.3.8. The vulnerability is related to the embedding model update feature under admin settings. When a user updates the model path, the system checks if the file exists and provides different error messages based on the existence and configuration of the file. This behavior allows an attacker to enumerate file names and traverse directories by observing the error messages, leading to potential exposure of sensitive information.

An Insecure Direct Object Reference (IDOR) vulnerability exists in open-webui/open-webui version v0.3.8. The vulnerability occurs in the API endpoint `http://0.0.0.0:3000/api/v1/memories/{id}/update`, where the decentralization design is flawed, allowing attackers to edit other users' memories without proper authorization.

In version v0.3.8 of open-webui/open-webui, the endpoint /api/pipelines/upload is vulnerable to arbitrary file write and delete due to unsanitized file.filename concatenation with CACHE_DIR. This vulnerability allows attackers to overwrite and delete system files, potentially leading to remote code execution.
