Detailsinfo

A vulnerability, which was classified as problematic, has been found in Linux Kernel up to 5.0.14 (Operating System). Affected by this issue is the function do_hidp_sock_ioctl of the file net/bluetooth/hidp/sock.c. The manipulation with an unknown input leads to a command injection vulnerability. Using CWE to declare the problem leads to CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. Impacted is confidentiality. CVE summarizes:

The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character.

The bug was discovered 04/23/2019. The weakness was presented 05/10/2019 (Website). The advisory is shared for download at securityfocus.com. This vulnerability is handled as CVE-2019-11884 since 05/10/2019. The attack needs to be approached locally. Required for exploitation is a simple authentication. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1202.

The vulnerability was handled as a non-public zero-day exploit for at least 17 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 208605 (CentOS 7 : kernel-alt (RHSA-2020:0740)), which helps to determine the existence of the flaw in a target environment. The commercial vulnerability scanner Qualys is able to test this issue with plugin 172398 (OpenSUSE Security Update for the Linux Kernel (openSUSE-SU-2019:1407-1)).

Upgrading to version 5.0.15 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (208605) and SecurityFocus (BID 105388†). See VDB-124429, VDB-127125, VDB-133998 and VDB-134452 for similar entries. Once again VulDB remains the best source for vulnerability data.
