An attacker may exploit this vulnerability by sending crafted HTTP requests to the web-based administration interface of an affected system. A profitable exploit may permit the attacker to execute arbitrary instructions with root privileges on the underlying working system of the affected machine. Cyble additionally coated this vulnerability in a separate weblog.
CVE-2024-10914 is a important command injection vulnerability in end-of-life (EOL) D-Hyperlink network-attached storage (NAS) units. Unauthenticated attackers can exploit it to inject arbitrary shell instructions by sending malicious HTTP GET requests to susceptible D-Hyperlink NAS units uncovered on-line. Researchers noticed that attackers are exploiting the vulnerability with publicly obtainable exploit codes.
CVE-2024-11068 is a important incorrect use of privileged API vulnerability impacting the end-of-life D-Hyperlink DSL6740C modem. The vulnerability permits unauthenticated distant attackers to change any person’s password by leveraging the API, thereby granting entry to Internet, SSH, and Telnet providers utilizing that person’s account. Since D-Hyperlink just lately introduced that it’s going to not present patches or updates for this EOL product, the vulnerability poses a major danger to customers.
Vulnerabilities and Exploits on Underground Boards
CRIL researchers additionally noticed a number of Telegram channels and underground boards the place menace actors shared or mentioned exploits weaponizing vulnerabilities. These vulnerabilities embrace:
CVE-2024-39205: A important vulnerability affecting pyload-ng, variations 0.5.0b3.dev85 working underneath Python 3.11 or under. This vulnerability permits attackers to execute arbitrary code via crafted HTTP requests, which may result in full system compromise.
