CVE-2024-45770
Public on
Last Modified:
Description
A vulnerability was found in Performance Co-Pilot (PCP). This flaw can only be exploited if an attacker has access to a compromised PCP system account. The issue is related to the pmpost tool, which is used to log messages in the system. Under certain conditions, it runs with high-level privileges.
Statement
This issue is classified as Moderate rather than Important due to the specific conditions required for exploitation. Although it involves potential privilege escalation and file corruption, the vulnerability is contingent on an attacker having the ability to create symlinks within the /var/log/pcp directory. Additionally, the exploit requires pmpost to be executed as root in a particular context, which is not typical in standard operation. These prerequisites limit the likelihood and scope of the impact, making it less severe compared to vulnerabilities that could be exploited more broadly or easily by an unprivileged user.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authorities (CNA) source for its products and services (see Red Hat classifications ).
| CVSS v3 Score Breakdown | Red Hat | NVD |
|---|---|---|
| CVSS v3 Base Score | 4.4 | |
| Attack Vector | Local | |
| Attack Complexity | Low | |
| Privileges Required | Low | |
| User Interaction | None | |
| Scope | Unchanged | |
| Confidentiality Impact | Low | |
| Integrity Impact | Low | |
| Availability Impact | None |

My product is listed as "Under investigation" or "Affected", when will Red Hat release a fix for this vulnerability?
- "Under investigation" doesn't necessarily mean that the product is affected by this vulnerability. It only means that our Analysis Team is still working on determining whether the product is affected and how it is affected.
- "Affected" means that our Analysis Team has determined that this product is affected by this vulnerability and might release a fix to address this in the near future.
What can I do if my product is listed as "Will not fix"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Upgrade to a supported product version that includes a fix for this vulnerability (recommended).
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
What can I do if my product is listed as "Fix deferred"?
Available options depend mostly on the Impact of the vulnerability and the current Life Cycle phase of your product. Overall, you have the following options:
- Apply a mitigation (if one exists).
- Open a This content is not included.support case to request a prioritization of releasing a fix for this vulnerability.
- Red Hat Engineering focuses on addressing high-priority issues based on their complexity or limited lifecycle support. Therefore, lower-priority issues will not receive immediate fixes.
What is a mitigation?
I have a Red Hat product but it is not in the above list, is it affected?
Why is my security scanner reporting my product as vulnerable to this vulnerability even though my product version is fixed or not affected?
My product is listed as "Out of Support Scope". What does this mean?
