Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Disclosed: evidence found.
CVE published 8 Apr 2024
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2024-31047, organizations should first monitor for official patches or updates from the Academy Software Foundation and apply them promptly once available. In the absence of patches, restricting local access to systems running OpenEXR can reduce the risk of exploitation. Implement strict access controls and user privilege management to prevent unauthorized local users from executing potentially malicious operations. Additionally, consider sandboxing or containerizing applications that use OpenEXR to limit the impact of a crash. Review and enhance input validation and error handling in any custom code interfacing with OpenEXR to avoid triggering the vulnerable convert function with malformed data. Regularly audit and monitor system logs for unusual crashes or behavior related to image processing tasks. Finally, maintain up-to-date backups and incident response plans to quickly recover from any denial of service incidents.

Description

An issue in Academy Software Foundation openexr v.3.2.3 and before allows a local attacker to cause a denial of service (DoS) via the convert function of exrmultipart.cpp.

Impact

The primary impact of CVE-2024-31047 is a denial of service condition caused by a local attacker exploiting the convert function in OpenEXR. This can lead to application crashes or service interruptions, potentially disrupting workflows in environments relying on OpenEXR for image processing. Since the vulnerability requires local access with low privileges, remote exploitation is not feasible, limiting the attack surface. The lack of impact on confidentiality and integrity means sensitive data exposure or modification is not a concern. However, availability disruptions can affect production pipelines, especially in media, animation, and visual effects studios that use OpenEXR extensively. Organizations with automated image processing tasks or rendering farms could experience downtime or degraded performance. Although no known exploits exist in the wild, the vulnerability could be leveraged by insiders or attackers who have gained local access. Overall, the impact is limited but relevant for maintaining operational continuity in affected environments.

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
