Detailsinfo

A vulnerability was found in Automatic Bug Reporting Tool (Reporting Software) (the affected version unknown). It has been rated as problematic. This issue affects an unknown part of the component librpm. The manipulation with an unknown input leads to a link following vulnerability. Using CWE to declare the problem leads to CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Automatic Bug Reporting Tool (ABRT) allows local users to read, change the ownership of, or have other unspecified impact on arbitrary files via a symlink attack on (1) /var/tmp/abrt/*/maps, (2) /tmp/jvm-*/hs_error.log, (3) /proc/*/exe, (4) /etc/os-release in a chroot, or (5) an unspecified root directory related to librpm.

The bug was discovered 04/15/2015. The weakness was presented 06/26/2017 by Andy (oss-sec). The advisory is shared at openwall.com. The identification of this vulnerability is CVE-2015-3315 since 04/16/2015. An attack has to be approached locally. A simple authentication is necessary for exploitation. Technical details are unknown but a public exploit is available.

The exploit is available at exploit-db.com. It is declared as highly functional. The vulnerability was handled as a non-public zero-day exploit for at least 61 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 84197 (CentOS 7 : abrt (CESA-2015:1083)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 155249 (Oracle Enterprise Linux Security Update for abrt (ELSA-2015-1210)).

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (44097), Tenable (84197) and SecurityFocus (BID 75117†). See VDB-102812, VDB-102813, VDB-102815 and VDB-102830 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
