TL;DR
CISA identifies CVE-2015-5287, a privilege-escalation vulnerability in Red Hat’s Automatic Bug Reporting Tool, as actively exploited. The flaw requires local access and certain permissions, while the affected versions, exploitation scale and identified threat actors are not specified in the supplied information.
CISA’s Known Exploited Vulnerabilities catalog identifies CVE-2015-5287, a privilege-escalation flaw in Red Hat’s Automatic Bug Reporting Tool, as actively exploited. According to the catalog information, a local user with certain permissions could gain higher privileges through a symlink attack, making the issue a current remediation priority for systems that still contain an affected ABRT installation.
The confirmed technical description places the vulnerability in Red Hat ABRT and identifies privilege escalation as the impact. Exploitation involves a symlink attack involving a file, although the supplied description does not provide the file name or all conditions needed for a successful attempt. The stated requirement for a local user means the available information does not establish that the flaw can be exploited directly by an anonymous attacker over the internet.
The CISA KEV classification indicates that exploitation has been observed outside a laboratory setting. It does not, by itself, identify the attackers, their targets, the number of compromised systems or the campaigns in which the vulnerability was used. The distinction matters: active exploitation is confirmed, while the scale and purpose of that activity remain unspecified in the provided material.
Local Access Can Become Greater Control
A privilege-escalation vulnerability can allow an attacker or unauthorized user who already has some access to obtain more powerful system permissions. That can increase the damage from a stolen account, exposed service or other initial foothold. For defenders, the KEV status changes CVE-2015-5287 from an older theoretical risk into an observed exploitation concern.
The practical risk will vary by environment. Systems that do not have an affected ABRT package are outside the described product scope, while machines with the tool installed still require review. Administrators also need to examine local account access and the permissions available to users because those conditions form part of the stated attack path.

An Older CVE Returns to Focus
CVE-2015-5287 carries a 2015-series identifier, placing it among vulnerabilities documented years before its current KEV prominence. Its appearance as an actively exploited issue shows why older software flaws can remain relevant when legacy packages or unpatched systems continue operating.
ABRT is Red Hat’s Automatic Bug Reporting Tool. The vulnerability description points to a symbolic-link attack, a class of weakness in which a file reference can redirect an operation to another location. The source material does not provide enough detail to establish the exact affected file, package releases or platform configurations.
“Red Hat Automatic Bug Reporting Tool (ABRT) contains a privilege escalation vulnerability.”
— CISA Known Exploited Vulnerabilities catalog description
Campaign Scope and Affected Builds Unknown
The supplied information does not identify affected ABRT versions, supported operating-system releases, available patches or the date exploitation was first detected. It also does not name victims or threat actors, describe the initial access used in observed incidents, or say whether attacks are widespread or narrowly targeted. The exact permissions required from a local user and the remaining portion of the file-related technical description are also absent, so those details should not be inferred from the KEV classification alone.
Administrators Must Trace ABRT Exposure
Security teams should identify systems running Red Hat ABRT, compare installed package versions with current Red Hat and CISA guidance, and apply vendor-approved fixes or mitigations where applicable. They should also review local-user permissions and investigate unexpected privilege changes or file activity on exposed hosts. Further CISA or Red Hat advisories may clarify affected releases, remediation deadlines and the observed exploitation pattern.
Key Questions
What is CVE-2015-5287?
It is a privilege-escalation vulnerability in Red Hat’s Automatic Bug Reporting Tool. The supplied description says a local user with certain permissions could exploit it through a symlink attack involving a file.
Can CVE-2015-5287 be exploited remotely?
The available description specifies a local user and certain permissions as prerequisites. It does not establish a direct, unauthenticated remote attack route, though another weakness could potentially provide the initial local foothold.
Does the KEV listing mean every vulnerable system was attacked?
No. The listing supports that exploitation has occurred, but it does not show that every affected machine is compromised. The supplied material gives no figure for attack volume or victim count.
Which Red Hat versions are affected?
The source material does not list affected versions or packages. Administrators should match their ABRT installations against current Red Hat security guidance rather than assuming that every release is vulnerable.
What should organizations do now?
Organizations should inventory ABRT installations, review the permissions granted to local users, follow official remediation guidance and monitor exposed systems for unexpected privilege changes. Unsupported installations may require replacement or removal if no supported correction is available.
