Rewterz penetration testing services help organizations determine if a cyber attacker can gain access to their critical assets while giving them detailed insights of the overall business impact of a cyber attack.
Before Rewterz got its start, the market was in dire need of a specialized and dedicated information security company. It was nearly impossible for businesses to find a trustworthy provider that could truly cover all of their bases. We wanted to meet this need, giving companies across the globe a chance to get ahead while knowing that their data is in good hands.

CVE-2022-47939 CVSS:10
Linux Kernel could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free flaw in ksmbd in fs/ksmbd/smb2pdu.c. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVE-2022-47938 CVSS:4.3
Linux Kernel is vulnerable to a denial of service, caused by an out-of-bounds read flaw in ksmbd in fs/ksmbd/smb2misc.c. By sending a specially-crafted request, a remote authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CVE-2022-47946 CVSS:6.2
Linux Kernel is vulnerable to a denial of service, caused by a use-after-free flaw in the io_sqpoll_wait_sq function. By sending a specially-crafted request, a local attacker could exploit this vulnerability to cause the system crash.
CVE-2022-47943 CVSS:9.6
Linux Kernel could allow a remote authenticated attacker to obtain sensitive information, caused by an out-of-bounds read flaw in ksmbd when there is a large length in the zero DataOffset case. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a denial of service condtion.
CVE-2022-47942 CVSS:8.5
Linux Kernel is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the set_ntacl_dacl function in ksmbd. By sending a specially-crafted request, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system.
CVE-2022-47941 CVSS:5.3
Linux Kernel is vulnerable to a denial of service, caused by a memory leak flaw in ksmbd in fs/ksmbd/smb2pdu.c. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVE-2022-47940 CVSS:8.1
Linux Kernel could allow a remote authenticated attacker to obtain sensitive information, caused by an out-of-bounds read flaw in ksmbd in fs/ksmbd/smb2pdu.c. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
