CVE-2015-8651 is a high-severity integer overflow vulnerability present in Adobe Flash Player, affecting versions prior to 18.0.0.324 and 19.x and 20.x before 20.0.0.267 on Windows and OS X, as well as prior to 11.2.202.559 on Linux. Additionally, Adobe AIR versions before 20.0.0.233 are impacted. This vulnerability allows attackers to execute arbitrary code via unspecified vectors, which poses a significant risk to organizations.
With a CVSS score of 8.8, this vulnerability is classified as high severity. It is critical to address this issue as it provides an attack vector through the network, requires low attack complexity, and does not need any privileges, although user interaction is required for exploitation. The potential impact on confidentiality, integrity, and availability is high, making this vulnerability particularly dangerous.
The urgency for remediation is underscored by the fact that this vulnerability has been included in the Known Exploited Vulnerabilities (KEV) catalog since May 25, 2022. Organizations using Adobe Flash Player are advised to disconnect the impacted product, as it has reached end-of-life status. This vulnerability may still be present in environments that have not migrated to more secure alternatives.
Organizations should prioritize patching immediately to mitigate the risks associated with CVE-2015-8651. Given its high severity and the potential for exploitation, proactive measures are essential to protect sensitive data and maintain operational integrity.
Vulnerability Details
The vulnerability description indicates that an integer overflow in Adobe Flash Player and related products before specified versions allows attackers to execute arbitrary code. This vulnerability falls under the CWE-190 category and has been analyzed thoroughly, confirming its high impact on systems.
The affected products include Adobe Flash Player, Adobe AIR, and various Adobe SDK components. The published date of this vulnerability is December 28, 2015, and it remains relevant due to the widespread use of these products at the time.
Technical Analysis
The root cause of this vulnerability is an integer overflow which occurs in the handling of inputs, leading to potential execution of arbitrary code. The attack vector is network-based, indicating that attackers can exploit this vulnerability remotely. While the attack complexity is low, user interaction is required, meaning that an unsuspecting user must trigger the exploit, potentially by opening a malicious file or link.
Privileges are not required to exploit this vulnerability, which increases its risk profile. The impacts are severe, affecting confidentiality, integrity, and availability, thereby allowing attackers to compromise sensitive systems without needing elevated access.
Risk & Impact Analysis
Risk to organizations includes the potential for arbitrary code execution, which could lead to data breaches, system compromise, and significant operational disruption. The blast radius for this vulnerability is considerable, given that Adobe Flash Player was widely used across various platforms and applications, increasing the likelihood of exploitation.
Organizations must assess their exposure to this vulnerability and act accordingly, especially since it has been included in the KEV catalog, which indicates active exploitation in the wild. The urgency is critical, as attackers may leverage this vulnerability to gain unauthorized access to systems.
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | Yes |

Affected Versions
All versions of Adobe Flash Player prior to 18.0.0.324, 19.x and 20.x before 20.0.0.267, and all versions of Adobe AIR before 20.0.0.233 are affected. Additionally, various versions of the Adobe AIR SDK and Compiler are also impacted. Organizations should verify their versions against the criteria provided.
Mitigation & Remediation
Adobe has issued patches for affected versions of Flash Player and AIR. Organizations should immediately upgrade to the latest versions. If patching is not possible due to end-of-life status, consider disconnecting affected systems from the network to mitigate risks.
Further, organizations can strengthen their defenses by implementing network segmentation, user training, and monitoring for suspicious activity related to these vulnerabilities.
For comprehensive security, organizations may also consider engaging in penetration testing to validate their security posture against such vulnerabilities.
Detection Guidance
Monitoring for unusual application behavior and network activity can help detect potential exploitation attempts. Organizations should ensure logging is enabled for all systems running affected software, and review logs for any anomalies or unauthorized access attempts.
AppSecure Threat Intelligence Insight
CVE-2015-8651 exemplifies the ongoing risks associated with legacy software that has reached end-of-life. Organizations using such software must recognize the increased likelihood of exploitation and take proactive measures to safeguard their environments.
As attackers continuously evolve their tactics, it is imperative for security teams to stay informed about vulnerabilities like CVE-2015-8651. Regular assessments and updates to security practices are essential to mitigate the risks posed by both known and emerging threats.
Organizations should invest in application security assessments to identify vulnerabilities before they can be exploited.
Additionally, engaging in red teaming exercises can provide valuable insights into organizational weaknesses and help prioritize remediation efforts.
In conclusion, CVE-2015-8651 serves as a reminder of the critical need for ongoing vigilance and robust security practices in an ever-evolving threat landscape.
