Seclog - #153
“If you know your network and your systems, you need not fear the result of a hundred cyber battles." - Sun Tzu, The Art of Cyber War
In this week's Seclog, the focus encompasses critical vulnerabilities, evolving security tools, and foundational debates shaping our digital landscape. We see alerts for supply chain risks, exemplified by a Rust crate vulnerability allowing arbitrary file writes, and a significant tenant-to-tenant escalation flaw in Supabase Cloud. Network operational resilience is underscored by Cloudflare's post-mortem on a non-malicious outage, highlighting the complexities of large-scale infrastructure. Simultaneously, research reveals persistent privacy concerns through WhatsApp's large-scale phone number enumeration vulnerability. The discourse on security practices is vibrant, covering the practical challenges of running bug bounty programs, the nuanced efficacy of VPNs for public WiFi privacy, and the increasing integration of AI into penetration testing methodologies. New open-source tools, from a ModSecurity-based WAF gateway to an SQL injection exploitation framework, illustrate the continuous development in both defensive and offensive security capabilities.

astral-tokio-tarcrate allows for arbitrary file writes via path traversal, effectively reintroducing "Zip Slip" style risks to the Rust ecosystem.
Developers utilizing this crate for archive extraction must upgrade immediately, as this flaw enables attackers to overwrite sensitive system files or achieve code execution during the seemingly benign process of unpacking data.
WhatsApp User Enumeration Tool
SBA Research releases a proof-of-concept tool demonstrating the feasibility of large-scale user enumeration on WhatsApp by exploiting the platform's contact discovery mechanisms.
This release underscores a significant privacy design flaw where the lack of strict rate limiting allows adversaries to validate phone number existence and scrape profile metadata at scale for OSINT or targeted phishing campaigns.
Albatar SQL Injection Framework
Albatar offers a specialized framework for exploiting complex SQL injection vulnerabilities, focusing on scenarios where standard tools like SQLMap might struggle with unique WAF rules or obscure database behaviors.
