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

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.

All across the Asia-Pacific region, large and diverse marketplaces for AI cybercrime tools have developed, with deepfakes proving most popular.

### 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. Refer to the links below for more information: - https://security.stackexchange.com/questions/195563/why-is-sha-256-not-good-for-passwords - https://stackoverflow.com/questions/11624372/best-practice-for-hashing-passwords-sha256-or-sha512 - https://cheatsheetseries.owasp.org/cheatsheets/Password_Storage_Cheat_Sheet.html#pre-hashing-passwords-with-bcrypt ### PoC N/A ### Impact It leaves users susceptible to rainbow table attacks

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.
