Zimbra has disclosed a new RCE vulnerability in its SMTP server. The vulnerability arises from improper sanitation, which can lead to a maliciously crafted CC line being executed as shell commands by the server. Researchers at Proofpoint report that there have been attacks since September 28 attempting to exploit this vulnerability and urge immediate patching.
A new Linux malware called Perfctl is targeting millions worldwide by mimicking system files to avoid detection. This sophisticated malware compromises Linux servers for cryptomining and resource hijacking, using rootkit and evasion techniques to hide its presence. To protect your Linux systems, update regularly, conduct vulnerability assessments, and use security tools like firewalls.
Over 4,000 Adobe Commerce and Magento e-stores were hacked due to a critical vulnerability, CosmicSting (CVE-2024-34102), which allows attackers to execute arbitrary code. The attacks have impacted major organizations and resulted in the installation of payment skimmers on victim stores. Merchants are urged to update their systems immediately to protect against these exploits.
Opaque predicates are a conditional expression that the programmer knows the answer to but chooses to check anyway. They can be utilized to obscure the control flow for anti-reversing. This post utilizes the MIASM Python library to create an IDA Pro plugin to detect and patch unreachable blocks. The plugin utilizes the Symbolic Execution engine to detect opaque predicates and then patches them with NOPs.
This blog post discusses how to hack Cloudflare R2 buckets to discover sensitive files. Begin by utilizing Google dorking and examining HTTP requests to discover R2 buckets. Exploitation can then be done via abusing missing or improper authorization checks or finding exposed R2.dev buckets.
