CWE-77 refers to the improper neutralisation of special elements used in a command. These special elements, when inadequately sanitised, allow attackers to inject malicious commands that the system interprets and executes. This vulnerability commonly appears in applications that dynamically construct system commands based on user inputs.
Out-of-bounds write vulnerabilities (CWE-787) are among the most dangerous weaknesses in software development. If left unchecked, these vulnerabilities can have significant repercussions, including data corruption, service outages, and, in the worst cases, remote code execution.
An out-of-bounds write occurs when a program writes data outside the bounds of allocated memory, causing code compromise in the software.
OpenWRT, while highly customisable, is not immune to the common security flaws that affect embedded devices. These can range from default configurations to poorly secured web interfaces
What is ACRStealer?
ACRStealer is an **info stealer malware** designed to **extract sensitive information** from infected systems, including:
– **Antivirus identification** – determining which security solutions are present to evade detection.
– **Crypto wallet theft** – targeting stored cryptocurrency assets.
– **Login credentials theft** – stealing usernames and passwords for financial services, corporate accounts, and personal data.
– **Browser information extraction** – harvesting stored passwords, cookies, and browsing history.
– **File Transfer Protocol (FTP) credential theft** – compromising access to cloud and remote servers.
– **Text file harvesting** – reading and extracting information from text documents.
While information stealers are not new, **ACRStealer stands out** due to its **stealth tactics, sophisticated distribution, and abuse of legitimate cloud platforms**.
SSRF vulnerabilities occur when an API fetches a remote resource using a user-supplied Uniform Resource Identifier (URI) without adequate validation. This oversight allows attackers to manipulate the request, coercing the server to interact with unintended destinations. These attacks bypass traditional network controls like firewalls and VPNs, making them particularly insidious.
