Pcp: pcp: arbitrary file creation via path traversal in pmproxy logger servlet
An unauthenticated remote attacker can exploit a path traversal vulnerability in the PCP pmproxy logger servlet using a crafted hostname. This allows arbitrary file and directory creation, potentially leading to a denial of service.

Pcp: pcp: remote denial of service and information leakage
A flaw was found in the PCP (Performance Co-Pilot) `pmproxy` service. A remote attacker can exploit a vulnerability in the `pmLogLoadInDom()` function by sending a specially crafted request. This bypasses a critical bounds check, which can lead to the `pmprox…

Pcp: pcp: denial of service due to signed integer overflow
A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet …

Pcp: pcp pmproxy: unauthenticated access to /store endpoint allows bypassing pmcd access rules
An unauthenticated remote attacker can bypass access controls by sending crafted requests to the PCP pmproxy /store endpoint. This allows the attacker to overwrite any PMDA metric, leading to arbitrary code execution and system takeover.

Pcp: pcp: privilege escalation to root via linux_sockets pmda vulnerability
A flaw in the PCP linux_sockets module exposes an unsecured internal connection. An attacker with initial code execution can exploit this to escalate privileges and execute arbitrary commands as root.

Pcp: pcp linux_sockets pmda: arbitrary command execution via command injection
A command injection flaw in PCP's linux_sockets PMDA allows malicious shell metacharacters via the network.persocket.filter metric. This failed validation lets attackers execute arbitrary commands as the PMDA user when metrics refresh.

Pcp: pmpost symlink attack allows escalating pcp to root user
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 conditi…

Pcp: pmcd heap corruption through metric pmstore operations
A vulnerability was found in Performance Co-Pilot (PCP). This flaw allows an attacker to send specially crafted data to the system, which could cause the program to misbehave or crash.

Pcp: exposure of the redis server backend allows remote command execution via pmproxy
A flaw was found in PCP. The default pmproxy configuration exposes the Redis server backend to the local network, allowing remote command execution with the privileges of the Redis user. This issue can only be exploited when pmproxy is running. By default, pm…

Pcp: unsafe use of directories allows pcp to root privilege escalation
A vulnerability has been identified in the Performance Co-Pilot (PCP) package, stemming from the mixed privilege levels utilized by systemd services associated with PCP. While certain services operate within the confines of limited PCP user/group privileges, …
