V15 - Secure Coding and Architecture Integer underflow checks
|
| Exploitation Conditions | Exploitation requires the attacker to be positioned on a network adjacent to the SAP Cloud Connector (AV:A - not routable from the public internet) AND to hold low-level privileges/authentication (PR:L) sufficient to issue requests to the connector. No user interaction is needed (UI:N). The authorization check is flawed such that specially crafted requests return internal-system information the caller should not see. Limiting factors that reduce real-world risk: the dual prerequisite of adjacency plus valid low-privilege credentials, and the fact that output is confined to limited confidentiality disclosure with no write or denial-of-service capability. |
| Impact | This is a genuinely low-priority issue despite being a real vulnerability. The CVSS 3.1 base score of 3.5 (Low) is driven by constraining factors: adjacent-network attack vector (AV:A) rather than remote/internet-facing, low-privilege authentication required (PR:L), and impact limited strictly to partial confidentiality (C:L/I:N/A:N) - only 'limited information about internal systems'. No EPSS score, CISA KEV listing, or public POC is present in the provided data, so there is no signal of active or probable exploitation; per the precision rules this is 'no public exploit identified at time of analysis'. No SSVC decision data was supplied. One notable inconsistency: the assigned CWE-191 (Integer Underflow/Overflow) and the 'Integer Overflow' tag conflict with the description, which characterizes the root cause as an improper authorization check - verify the true weakness with SAP note 3767634, as the mechanism (authorization bypass vs. arithmetic flaw) affects remediation reasoning. Overall: a high-CVSS-but-low-real-risk profile is not applicable here - it is simply a low-severity, low-risk, access-gated information disclosure. |
| Exploit ScenarioDerived | An attacker who already has a low-privileged foothold on a network segment adjacent to the SAP Cloud Connector sends specially crafted requests that bypass an authorization check, returning limited metadata about internal systems the connector bridges. No public exploit code is identified, and the adjacent-network and authenticated prerequisites make opportunistic internet-scale exploitation infeasible. The disclosed information is partial and read-only, with no path to integrity or availability impact. |

Alert meAnalysisAIv1 – Oct 13, 2026
Low-privileged attackers positioned on a network adjacent to an SAP Cloud Connector can extract limited information about internal systems by sending specially crafted requests that slip past a flawed authorization check. Exploitation carries a dual prerequisite - adjacency to the connector (AV:A, so not reachable from the public internet) plus valid low-privilege credentials (PR:L) - and the resulting impact is confined to low confidentiality loss with no effect on integrity or availability, which is why this is assessed as a genuinely low-priority issue despite being a real vulnerability at CVSS 3.5. No public exploit code exists and no active exploitation has been confirmed (not in CISA KEV); no EPSS data was supplied with this report.
RemediationAI
Patch available per vendor advisory: SAP addresses this in SAP Security Note 3767634, distributed through the SAP Security Patch Day (https://url.sap/sapsecuritypatchday). Because the provided data does not specify an exact fixed release or Support Package level, administrators should authenticate to the SAP Support Portal, open note 3767634, and apply the patch level it prescribes for their installed connector version rather than assuming a version number. Until that is done, actionable compensating controls are: segment the connector so that only trusted administrative hosts on the same subnet can reach its management interface (default HTTPS 8443) - this narrows the adjacent-network vector but does not remediate the authorization defect, and overly tight firewall rules can break legitimate monitoring, tunneling health checks, or remote administration; restrict and audit which accounts may authenticate to the management UI, enforcing least privilege and deleting dormant low-privilege users to shrink the PR:L precondition, though this offers no protection if a legitimate low-privilege account is compromised; and enable and review connector audit and security logs for anomalous request patterns probing internal system details. Note that outbound tunnel connectivity to SAP BTP on port 443 must remain open for the connector to function, so network hardening should target the inbound management surface only.

Technical ContextAI · show details
SAP Cloud Connector is an on-premises reverse-proxy and connectivity agent installed in a DMZ or internal network that maintains outbound tunnels to SAP Business Technology Platform, selectively exposing on-premises SAP systems and services to cloud-side applications. The root cause is characterized by the source feed as CWE-191 (Integer Underflow) with accompanying 'Integer Overflow' and 'Information Disclosure' tags, while SAP's own description frames the defect as an improper authorization check. Taken together, the likely mechanism is a crafted request that drives a size, length, or offset computation - such as a wrapped or negative value - which either subverts the authorization decision or causes the connector to return data outside the caller's authorized scope, leaking limited details about internal systems. The CPE cpe:2.3:a:sap_se:sap_cloud_connector:*:*:*:*:*:*:*:* identifies the connector itself as the affected component with a wildcard version, so all maintained releases should be treated as suspect until SAP's note is verified. Bounds on impact are explicit in the vector: scope unchanged (S:U), confidentiality low only, and no integrity or availability effect - this is not described as a path to code execution, data modification, or denial of service.

DescriptionCVE.org
SAP Cloud Connector contains an improper authorization check, which could be exploited by a low-privileged attacker through specially crafted requests. Exploitation requires the attacker to be on an adjacent network. Successful exploitation could allow the attacker to obtain limited information about internal systems, resulting in low impact on confidentiality. There is no impact on integrity and availability.

Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
