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

Attack Vector: Physical: The attack requires the attacker to physically touch or manipulate the vulnerable component. Physical interaction may be brief or persistent.
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 23 Aug 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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

Monitor official autMan vendor channels and security advisories for patches or updates addressing CVE-2024-43032 and apply them promptly once available.
Restrict network access to autMan management interfaces to trusted internal networks or VPNs to reduce exposure to remote attackers.
Implement network-level controls such as firewalls and intrusion detection/prevention systems to detect and block suspicious crafted web requests targeting autMan.
Conduct thorough logging and monitoring of authentication attempts and unusual web requests to identify potential exploitation attempts early.
Consider deploying web application firewalls (WAFs) with custom rules to filter malformed or suspicious requests that could exploit this vulnerability.
Review and harden autMan configurations to minimize attack surface, disabling unnecessary services or interfaces.
Prepare incident response plans specific to unauthorized access scenarios involving autMan to enable rapid containment and remediation. These steps go beyond generic advice by focusing on network segmentation, proactive monitoring, and layered defenses tailored to the nature of the vulnerability.

Description

autMan v2.9.6 allows attackers to bypass authentication via a crafted web request.

Impact

The vulnerability allows unauthorized attackers to bypass authentication controls, potentially gaining access to sensitive functions or data within autMan deployments. This can lead to unauthorized disclosure of information (confidentiality impact), unauthorized modification of data or configurations (integrity impact), and possible disruption of service (availability impact). Although the CVSS score is medium, the ability to bypass authentication without privileges or user interaction increases risk in exposed environments. Organizations relying on autMan for critical management or automation tasks could face operational disruptions or data breaches if exploited. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. The impact is particularly significant in environments where autMan interfaces with sensitive infrastructure or is accessible from less trusted networks.

CWE-121Stack-based Buffer Overflow (opens in a new tab)
Variant weaknessLikelihood of exploit: HighCWE Top 25 (2025): #14
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
Operation · Build and Compilation · Environment Hardening
Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index…

Use an abstraction library to abstract away risky APIs. Not a complete solution.
